Geomorphology and Landforms || lecture 5 || parmar sir ssc 3.0 geography || Geography

0:20 I am from Israel ok Raju Kumar let's start today's session People's lecture is going to be TWICE B JIO Muffled and Different Kind of Land Forms This is Our World Geography We have two more lectures left after this. After that we will study Indian Geography we will start okay after this our mainly which is the atmospheric part and which The part which is water is ours in which we will see clouds etc but which we have in a way interpreted to mean I had started studying interiors etc. The last lecture in the series is our kiss sense I'll look at whoever is there so far yes good morning everyone sir i dis Sufficient for CPF Tell this thing many times in AC sufficient

1:08 I have done it every time with the same sufficient Your messages keep coming, I keep reading that I won't be able to tell you anything, anyway, here So far we have studied the interior of the Earth Read about the interior of the okay earth read about i.e. the internal structure of the earth this is what we call in geology comment I will quickly tell you who is known as the father of geology in this lecture what we are going to do that is jiomar for jii jiomar what do we read in fol ji that the meaning that has a surface and its topography is how it is How were mountains etc. created? How were they created that we can speak that the things that are made or destroyed Even the thing related to meaning is existing with us How they were created on the surface is what we know

1:55 Let's read Geo Morpho in Ji then Father of We studied geology with James Hutton. By the way here is the Father of Geo Mofolactic How many students are there here right now? I will see it is 5.3 ok and a half paisa By the way friend don't send it, okay I am here Dhama Sir Sir, you must remember Vijay Pat in Agniveer

2:41 I was a student sir, I was on duty yesterday Sir did my SSC 3.2 test take place I missed it yes Mayank there was no test yesterday, test is today it must be so and I have definitely recognized it no yes so the test was not done yesterday and today He will be tested, I am fine Do your job comfortably, there is no problem Well, those of us who don't know me are quite If you are an old student then you would have come right away hey jiyo mofos p then it's like the life of all of us There are more than 5000 people here students are the ones who are currently watching So what is there in your life? the things that are making you or I will tell you that you are building it, okay What are you building in your life? Are you watching any motivational video?

3:27 did I insult you or did I mean anything means you are reading so what are you that Are you studying or exercising? yes if you are learning some new skill then all these I'll keep things build that means you you are building what is the other side are getting destroyed ho, how are you getting destroyed? you are destroyed you are getting destroyed by destruction Maybe a friend told you something wrong

5:03 All those things are interior to you do I have to take a decision from you or not friend I will not disclose, I will study You have to bring all those things from inside. What are exogenic? okay endogenic and it becomes one meaning will we become two layers on the surface of or else It determines which path we take Good habits are being followed more by holding on to them Habits or bad habits are habits that will build those habits for us or else The habits that destroy us which are going to stop our growth Similarly, there are two types of surface of the earth Forces are applied due to which there are two types of processes, one is endogenic the process which is called the internet and exogenic became one which It's endogenic, it builds things up what does it do builds things

5:48 Builds where that floor is coming from it's coming from within like if you yourself If you want to build then the one who is calling all those things are motivation interior You have to take the decision yourself No, I am not a procrastinator If I study, I will do all those things From inside you have to colonize exogenous What are those things that are on our earth's surface There are different relief features Relief feature is What is the meaning of relief features in geography? Mountain plot means whatever is made ok we call it relief feature different types of land forms which they get destroyed, is it okay or else their Wear and tear is exogenous processes or exogenic forces The processes that occur as a result of We are Exogenic A Exogenic Forces processes that occur because of We call them exogenic processes. So because of that wear and tear occurs What is the reason of all this because of the outside forces So we call such forces exogenic forces. Now let's talk about them in detail let's read it like this is the first one in the geom geomer fic process that our what are endogenic processes endogenic processes then endogenic

6:33 Processes are those processes that are caused by endogenic forces We call them endogenic processes. Look everywhere on our earth's surface There also appear to be endogenic and exogenic Forces are also being felt, Endo is also being felt and it also seems like now who looks more beautiful who is looking less will determine that things will be built there or you will be destroyed like I am to you I will give you an example like our Himalayas And Aravali is the best example You should know by now that the Himalayas is our one of the tallest you know structures are all over the earth's surface and Aravallis are not that tall but at one time Aravalli used to be higher than Himalayas What happened that Aravali has no meaning today There are not many names and traces, and the Himalayas Its region is so high that it is It is not that there are endogenic forces here You may seem to be here and only here Exogenic forces may seem like this It happens that which one looks more at which place Here endogenic forces are more prevalent Are you a comparison to exogenous?

7:19 What is in the Himalayas and Aravallis? Exogenic means the force that comes from outside is more You must be looking age compared to the difference between that is endogenic forces so which are the forces I'm talking about endogenic forces. Those who build things, their The processes that are generated because of this we call them Now who are they called endogenic processes? If they come to know that there are forces Endogenic Firstly, we understand that What happens because of endogenic forces things happen on our earth surface Our earth surface consists of two things One of the reasons for this is deitro fism and the other one is that is called edge vulcanicity i can say that it is endogenic because of the forces that we have things that build, build they get elevated okay they get elevated we say all this we say all this If we talk about diastrophism in Hindi then What is meant by plate deformation? Things come first in diastrophism

8:08 orogenic movements or orogenic processes orogenic What does oro mean in geography? mountains are orogenic processes are the ones who build mountains now How are mountains built and how many all those things are of types when we If you read about mountains then there You will see that mountains are of different types okay so the mountain building These processes are called orogenic processes say others are ours Papyro Jannik Arrow What processes are genic and aerogenic? who builds everything other than mountains do that means I can say that the our earth crust is fine which is different let's build the parts ok simply Uplifting if I may speak

8:56 Parts of Earth's Crust earth's crust crust you know our The topmost layer of the Earth is called Orogenic movement when we talk about crust Orogenic processes are what create mountains are building mountains Apart from this, the movements which are taking place are of the meaning It was as if some plateaus had formed on the crust Once the uplifted part is formed then it is called aerogenic The third one is kept inside the movement here is our earthquake whatever forces are being applied inside plate tectonics is happening because of that That is, the plate tectonic movement which If we speak in Hindi then it means plate We have read tectonics, please comment I will tell you how much plate movement Do you know what type of volcanism it is? from inside which magma or lava comes out We know it as volcanism.

9:43 Now first I will tell you what the answer will be There are three types of plate tectonics We had read that one is a convergent plate Boundary divergent and transform Crust is destroyed in convergence Subduction zone is created in divergence New crust gets constructed that's why It is called a constructive plate boundary There is lateral sliding in the trans Because of which neither crust is created nor It gets destroyed, now the point is that this Where are endogenic forces coming from So what is the energy behind them? Where is the energy coming from sir endogenic You have read about the forces why was the plate moving, did I I told you, tell me something quickly Forces told you that the plate is ours why does the plate move Move math channel sir ji please English channel too Give me a teacher for SSC who is like you

10:30 please read Sir when my wife gets my money then There is progress plate so what did I tell you Why do endogenic forces occur because our plate which is inside our earth lithospheric plates and one thing remember one thing I have to add one thing here and that is That where I told you about earthquakes I had taught about earthquakes there Note one thing that whatever our All those lithospheres are natural earthquakes come in the lithosphere whose What is the thickness of 200 km? What is the lithosphere? All of the crust plus the upper solid part of the mantle is called lithosphere so this is

11:16 If there is a plate, then when this plate moves the plate moves only that person It is because of this that it is called tectonics Earthquakes happen because of that only Mountains are mostly made, do not say this I am saying that the plates are moving because only mountains are formed from this but as Mountains like our Himalayas are plates If they are created because of the movement then this We read why the plate was moving that what was going on inside Where are convective currents developing inside pe ethnos ethnos then or what we call it which is magma okay so conve action current is developing there and this Who had put forward this theory? Who had put forward this theory? it was laid down by Arthur Holmes and then I told you that convection current why are they developing because of which This is creating a thermal gradient

12:02 The radios which actually develop Active DK is a radioactive D This is because of the thermal gradient is created i.e. in temperature Difference and hence convection current If they develop then one thing is radioactivity one region is done the first one is ok the second region Write here that is primordium we can say raced heat is ok prem or res heat hum you can say ok Residue heat means that when if meaning was created then whatever he already had heat was already present heat was already present We know it as residual heat. This is also a reason somewhere The different endogenic in the earth surface

12:48 forces are being applied to him, it is ok for you Also called Resid or Premordium Heat okay can you race or else primordium and the third one is that is We can also call it tidal force Actually Arthur Holmes came up with the concept Polar flying force and tidal force but tidal force is not actual but We call this rotational or tidal friction it means very, very little This too undergoes evolution, but very slowly. is minimal which is generated tightly The friction that is caused by that is tidal It is called friction and it is also mentioned somewhere Nor is there a slight role of endogenic in the forces but mainly what we have is ours One is radioactivity due to which convection currents develop in our In the Ethno Sphere, Arthur Holmes said And this is our premordium heat, okay There are these two forces due to which

13:34 plates etc move because of this the things that build us up It is built by us, we call it dietrophysics they say membrane distortion and this is One reason is our endogenous processes Now after this come exogenic processes going out force going inside going out going out ok eye showing okay well so exogenic process Now let's go to what is exogenous which do the wear and tear to the wear and tear on our earth surface those who work to spoil things we work now who will spoil it He who works to spoil our different agents do okay that different agents do it and those agents by what name do we know them exogenous agents such as wind

14:21 The wind is making things worse okay so the glaciers are moving What are glaciers doing? They are uprooting things. we are taking it okay it's windy It becomes a glacier or river water, so this what is different is the agents who Performs exogenous processes If I ask you this first thing, then it's ok first you tell me that whatever wind there is Water glaciers are all these agents what is a source of energy if i May I ask you what is the source of energy? So the source of energy is their sun you will read this gradually further that which This is because of the differential heating of the sun The wind blows and this is the reason behind your rainfall There are glaciers etc. somewhere or the other Directly and Wind is indirectly linked to the sun

15:08 Glacier water heat is all linked to the sun so what is the primary source of energy Sun is there for exogenous process what was this radioactivity residual heat and Tidal friction like I told you also our they are endogenic processes We would call it simple dyestuff is like any other exogenous process we call them with love what do denuded say dinedation or we can say that deposition means the deposition of things It has to deteriorate, we wear it inside say sorry in hindi and sorry in english we call it dend now inside the dend we have to then within the exogenic process there are three Things to read: Weathering Mass Movement and

15:55 Erosion or transportation, these three processes evolve that are denied In processes, that is, the processes which which causes wear and tear on our earth surface Driving force for weathering What is Energy Mainly Molecular Stress We will also study chemical action, weathering what is it, how does it happen, why does it happen What is a driving force behind the movement? is the gravitational force here It is not a force, it is gravitational stress gravitational force can exert mass here movement and erosion transportation of Kinetic energy is responsible for the back You won't understand it now, slowly slowly let us first come to the weathering okay Let us understand weathering. What is weathering? if it's a thing then weathering is simple if I If I talk about it, it is what we rock Breaking Bad

16:44 rocks that break or minerals They happen here and there, they break here and there by that I mean that breaking down of theirs is weathering it It is said that weathering is an in-situ process This process means that it doesn't do its play moves like it there is a rock there is a rock lying right here It broke suddenly, did it not move or Then if there is a negligible movement then because The process happened right where it was That is why it is called in satu process. Weathering It is now clear to us why our weathering is happening it can i.e. how many types are there then The first type that we have is that of weathering can be yours what can we say about this Chemical Withering OK is chemical

17:32 Chemical weathering becomes physical weathering will occur and a biological I have come to know about weathering chemical in Hindi We will call it chemical and physical weathering physical and biological weathering We will call it biological weathering now how does this weathering happen a little Just understand this briefly in detail No need to know it's a rock it's a rock ok there are many types in this too Like if I talk about all its types So just like there is a solution to the solution This means that, as here, there are cracks somewhere its okay and water is seeping out What happened here, it kept bothering him it will go on and on and on and on it'll break the rock and so on Carbonation happened What is carbonation such as carbon dioxide, which is our It is present in the atmosphere and in water

18:19 you will get it and If you study carbonium in chemistry then it will we'll break it or else or if we and what can What is Oxidation Oxidation also we will study in chemistry maybe you Some of the people might know that oxygen Adding so if it's too accessible oxygen is added, that reduction is so this If weathering occurs through any chemical process If it is happening then we call it chemical weathering Let's say physical weathering is physical first biological weathering read biological weathering happens as if our earth were a worm Gone are the insects and spiders which are our earthworms, i.e. that those which have become earth worms or rodents, etc. These which are ours They are small creatures, what do they do? it penetrates the rock slowly What do you do gradually, it gets its place

19:06 let's start making it, okay? Slowly and slowly you start making your place It's small and he wants to break it If we start from the inside then slowly it The rock starts getting weak and breaks Biological Weathering Physical Weathering It happens when there is stress etc. Because of whom did the stress fall on the rock? There could be stress if you do a lot of are you feeling more gravity or else There is a change in the temperature If change is taking place then we call it or Then let's assume that there is too much pressure If it is, then this is what we call it what's happening in it what's happening in it What are physical withering effects So, what are the effects of withering? as if this is an effect which they speak Exfoliation may be something some of you might have done Especially girls can go to beauty parlor

19:52 I got this exfoliation done Exfoliation is done in beauty parlors what happens that or else i came to the house also It happens that you applied some cream or something like that something like this cream type thing happens and Then if he is fired then it is your The top layer is just a thin layer of skin In which your dust particles etc. all the things are there then they go away and Your skin starts glowing Exfoliation happens in the same way here as well The difference that happens in our earth surface there are rocks there are rocks so if If there is a lot of temperature change Because of that, there would be expansion and contraction is in the rocks because of which the overlying It is a rock at the top, it breaks and falls and the rock that comes out from inside is absolutely It comes out shining, this is what is called Exfoliation question just came in CGL 2024

20:40 It is straight forward and exfoliation is the same we will do it, it's ok for him movement is ok mass movements what is this is this one your type or which one The effect is a withering knot type effect What is the mass movement of withering e.g. that here I or here first of all we People had seen that the process was denudation I read three, one is weathering We understood how weathering happens and why there is an init process and breaking Off frocks are always a mass movement When things move they mean a lot A large part of our earth's surface moves is it all at once or gradually its mass They call it movement, why does it move? because of gravity because of gravity Take care weathering this thing

21:26 is not a pre-requisite for mass movement the weathering that happens is not a prey Requisite Pre requisites for mass movement what does it mean It's not like that unless the weathering There won't be any mass until the rock breaks There will be no movement, meaning of mass movement a large portion occurs all at once or if it falls slowly towards the bottom then it They say mass movement, move suddenly That big part mass movement is not like this anymore that is, unless there is weathering in it till then it will not move at all, this means Weathering is not a pre-requisite for mass movement then why will it move It does this because of gravitational force is the main driving force and energy Behind the mass movement there is a mass movement

22:13 We have two types, one is Rapid which is absolutely it should happen slowly and gradually what comes in rapid like in rapid that our land slide Land slide happened, okay avalanche happened if a snowflake is falling We can also call that a rapid mass movement. are ok meaning Flow, mud flow, all these are our types There are types of rapid mass movement Where let's say suddenly there was a very loud If it rains, what happens to the land immediately? You must have seen slides in hilly areas It happens suddenly in hilly areas A piece of land suddenly fell down, now the land Slides also have many reasons so okay that gravity looks like it is a main factor but we don't put it in the environment

22:59 Read how to stop landslides If possible then how can land slide be stopped This can be prevented by afforestation Then what is the main reason behind the land slide it happens okay it happens it's okay The area is shaking due to gravity and rainfall is visible When it rains suddenly a landslide occurs It starts happening but the rate at which we Deforestation is cutting down trees If so, this is also a reason for land slide We will call it anthropogenic region i.e. that what is happening now is because of humans How deforestation is a reason for land slide because our roots are The roots of trees touch the ground it holds on to the soil it holds on to the soil So now because you cut down the tree, it It has become loose and will fall down immediately meaning Flow mud flow is also something like this that Let's assume this is a road, okay There is a road right here, what happened that here But it rained very heavily

23:45 When it rained it became very weak What is here because of being part and weak Soil Liquiflo is done It is because the swelling has become a bit weak if it is then it is called swal If Liquiflo comes on the road then we will tell him hain earth flow is ok let's come in slow like our Creep Soil Flexion Soil Liquiflo What it happens like soil what is liquefaction Soli flexion happens, we have to see this Provides cooling effect in temperate areas When the bottom layer of soil in the area

24:32 in which the water freezes slightly, that is Somehow a layer of ice forms on it so because of that what is it that the above The layer of soil that is there will slide more quickly. that will happen is called sole flexion That means we get to see it in temperate areas The name Creep is the same as Creep Creep It means ringing which happens slowly Slowly there is slight movement As you might have noticed, the pillars etc. you don't know it happens but they They become crooked, I don't know when they become crooked because whatever it is in the soil, whatever If it is in the soil then why slowly Slowly, slowly, she is moving So because of its movement, that pole The pillar is small and then it is a tower There was a slight tilt in the movement of the soil from the point of view of movement slowly This is called slow mass movement or Creep, everything is clear to everyone till here

25:18 This was our wish, it was fulfilled in this keep it in endogenic and exogenic what's the difference nisha you are late There is no doubt about anyone here What is the difference between earth flow and mud flow It is earth flow, mud flow, look both are same It is almost similar thing, it is same It is obvious that is why it is different It is like everything happens in the flow of the earth

26:04 all things are in the sense that they are made of stone the debris that is in the mud flow The soil debris is very This fluid is of very fluid nature It happens that it is not that fluid meaning In the flow and everything else in it is also a stone etc. are also contained in the meaning flow And this also should be on the basis of composition What kind of flow does it take? Meaning in which shape should it flow? in which shape are you flowing as if that whatever little shape the earth flow would have it's shaped something like this okay What happens to mud flow A little about mud flow a very mean turbulator shape what happens to mud flow so this is just a little There are differences that you will face in the exam He will not ask but if he asks you then he will He will ask brother which one is Rapid and Which one is slower than these? Just fine.

26:49 is soli fluctuation not soli fluctuation This is Shailesh Yadav this is Soli reflection Soli Flexion is a slow mass movement such as Our soil creeps slowly It is moving slowly because it is raining Let's assume it must have happened or it might be weak The soli flexion also happens in the same way But this is the case in temperate areas. The area is visible in the view where the soil under it is like the soil The bottom layer is permanently frozen what is that it's frozen it's frozen So we call that thing of his as Solly Fluctional is our second and final topic for today Lecture ka that is land forms due to Various agents who differ from our agents Which agents are What is Volke nism? Volke nism Sir, I have read it, okay, let me tell you Volcanism Why didn't I put it here?

27:35 I have taught you this, Vulcan jam because vulcan jam we have read all that's how the inside of a volcano comes out Which rock is formed from Plutonic rock? Which rocks are formed, what line forms are created, okay, and whatever our We have read about volcanoes yes you want to read as much as you want that's why you are here I have not taught you clearly, I will come soon There are land forms due to various agents So who are the different agents? From which I just told you about the agents who are our What are exogenous agents? as if our river had become The glacier has become like the wind has become like that our sea waves became like our ground water is fine so these things I am already ready to start this Let me tell you this beforehand

28:22 that it is not that important topic that it is a very important topic that every This type of question is coming in the shift This is not a topic, it's ok and a little bit Some people feel on the difficult side not everybody but some people The first thing it seems is that it is quite It is a big topic in itself like When I took classes in CDS etc. I liked two lectures in that, only this Land Forms in Teaching Particular Topic Due to various agents who are available for you I've had enough The consignor is saying that sir we are CDS Look for help for CPF in this way So he will do it but here my advice is this I will tell you a little bit about him Go from NCERT or any other book In a little detail if it is from NCERT If possible, it would be better that a little You can read about it in detail

29:08 about that particular thing anyway I will explain to you everything, as many lands as I can I will teach you everything about the forms I will tell you how to make it but just a little if Those who are CDS CPF can read it in detail If you are preparing after knowing this I am speaking for them, rest are SSC for I will teach you as much as I can that your work will be done comfortably questions will be made from this okay so this topic You do not have to read it with full load You have to read lightly, it is ok, same things as before Let it go inside and then revise You will slowly start remembering things on your own It's okay, I don't have to take any load because It is not that important topic but because questions come we will Do it and don't think that sir means so much After doing the compilation I have prepared it for you here If it has been presented on my blog then first of all you should see it These are the land forms created now

29:55 First they should understand what forms are hey look this is water okay okay river water It is ok, just relax and read it comfortably This topic should not be discussed in a very relaxed manner I can't even remember how it is it will not happen, no, no, all that will not happen, just relax Now it is river water for the purpose of understanding Correct This thing will be valid for everyone, whatever I tell you The Glacier Wand for the River Water seawaves groundwater when these move like suppose the water is running okay the water is running So what do you think about this slope which is like this has it been created, was it already made It was already made for the river and that brother A river is going to flow from here, so first they are not formed by the river on their own made, break, break, break, break brother obviously she will break it wherever she is going This is where the river is flowing from if there is gradient, if there is slope, then its because of that it will have velocity and because of that she will erode things now

30:41 this is your erosion this is your erosion erosion or Transportation and weathering are two different things. The mass movement is falling there now He is lying down, who will pick him up this will lead to erosion or else Transportation What is the energy behind it? Few people would know about kinetic energy some people might not know because Kinetic energy comes in physics like this Understand when something moves, when something moves If it does, the energy that it contains if it is then it is called kinetic energy Correct so because it has a gradient because There is a slope in it, what will happen because of it The kinetic energy of the moving body will be because of which what will it do, will it cause erosion will do Erosion and the land forms that result from it They will be called erosion land forms

31:27 If we talk about FMS in Hindi then the upper name is Updam Land Forms will say it is okay to them ⓘ Upper Namibia He took it somewhere and collected it too If she does then we call it dispositional Land form or what will you say in Hindi depositional landforms It is like this with everyone, the glacier will also break boils it will be called Rozan Land Farm will deposit those things somewhere where deposition land forms wind seawaves Ground water is the same, we are going to study it which things does one break and when does one break them If he breaks things then the land that gets damaged because of him A shape is formed which becomes a land form what do we call it like now what we have

32:12 It's in reverse, like coming out of a mountain from here Glaciers take their value sources like our Himalayan rivers If it is, then it is coming from the Himalayas, okay? Because it is located at a very high altitude our mountains which are shaken then when when this river will flow from here because If it comes out, there will be a lot of gradient If there is slope, then kinetic energy if it happens then what will happen here most First there is erosion there will be a lot of erosion then down when If it comes then what will be the deposition here Now our river water will be our river This is its entire edge Then there is a complete stage, we call them three ages the first one which Its stage is called youth full stage It is said that when it is in one's youth and when one is young, his

32:59 The velocity, the intensity is very high When the intensity of our river increases When is it the fastest? She is coming out from the mountain to the glacier where if there is a source then when it is coming out then If the flow is happening at very high speed We call it youth full stage when it Going from gradients to just flat planes If yes then we call it mature stage and when it reaches its final stage if so, we call it old stage ok now i said this because Sometimes he asks that this particular Land form is the geo shape of river water In which stage was it created by She becomes youthful in full maturity or old If I ask this way then firstly we you have to pay attention or you can easily understand that when she will be in the full youth stage then The things which you break too much will burst

33:46 That means erosional land forms will be created here First of all Rozal Land Forms Which are the erosion land forms It's made like what you can see this one it's called that shaped valley okay you see this is a valley of that size V Shaped Valley V Shaped Valley has become ours ok here i can write a Seconds are okay so this is a W shaped well I am writing it here, please take care Like this, if this becomes V shaped But if there are steep rocks both There are steep walls on both sides But it is in V shape right, but if Steep walls will be like straight rocks If there is, we will tell it

34:31 Gorgeous Gorgeous Not Gorgeous G O R ges and if something like this happens now What is its top and what is its bottom It is almost parallel, if something like this If it is made then we call it Canyons okay what happens in this is a little bit Kind of like that, the top one is narrow and the bottom is broader it happens okay so v shaped valley gorgeous and the canyon what is this this is your waterfall The waterfall which is a waterfall is also your erosion This is a land form, what is it called They say entrenched Mander entrenched Mander Mander we'll see now What is Mander Mander when any river It moves in the shape of a snake

35:17 is in a curved shape then it is mudding tell me what is this that is here River Terraces He will only ask you the name, who is brother Rojal? What is it and which dispositional is it Now when our water falls from the waterfall from the waterfall where it falls so yes There will be a crater because from very high up It falls wherever you go At the waterfall like I just had one The waterfall in the bar is the one I saw I heard that the waterfall is probably part of Himachal If you have heard the name Bhag then is it there or somewhere? If you look at it, it gets created instantly Why is it there because water is falling So let me tell him continuously, please

36:02 Pool intermittently in its path as if the value Let's take a big stone and then when the water It will come okay just like if water comes here the water will fall like this it will fall if it falls like this then here is a small If there is a pit, we call it a pot holes like those in our roads If there are pot holes in the road then it is just like a river The pot hole that is being created on the way, pot hole please pool what is this this is also rozan land Forms will be done, now comes the disposition in land form then disposition land form So the simple thing is that when the river Only then will it reach its mature and old stage It will deposit things, it will accumulate Because till now the gradient had a slope I was there so all those things on the slope which It was debris and he was walking along with it But as soon as you reach the slope the gradient ends The slope is over so now this is flat I have collected all the debris it will do ok so one of the things is this we

36:48 This is called Elvil Fan Elvil Fan Now how is this fan made You can see there was a slope, debris was coming As soon as a flat surface appeared suddenly All the debris of the fan got deposited here Sir this fan doesn't seem to be in shape son, I am talking about a hand fan remember your summers On time for summer vacation at uncle's When you used to go here, your grandmother would be here I used to take out the fan and give it to the one to whom you He used to call it Bijna and if he took it again then it would have been like that This is a fan of the same type, this is Elvil fan, this is ok what is this it is called levi now this Understand how it would have been made, just take it easy If you want to understand then I will tell you Levi That means I could have written that this is the regional and This is the deposition but I have taken the pictures That's why I put it in your mind that Things should be stored properly now when it is time for flood

37:36 It is like the time of June, July and August It was very much there in Gujarat and other areas There has been a flood, it's as if this is a river Now when the time of flood comes, the mouth of the river It will become wider because the water will rise more If I go into it, the river starts flowing like this now When the river's mouth widened, the river came here The river is flowing from here and has come till here The water has reached even in your village It would be like the river in your village It will be like when it rains suddenly It would have spread and could have reached your home Water comes as if our home is a village What is it that is near the river So the river sometimes comes up there If it rains a lot then when the river will come and when again Residual gene path was there so those are some things The deposit will also be made here from the river

38:24 Things must have come in the flow of These are called deposits If you understand Levi's then you are Levi's and you are an Elvil fan What is this, it is a depositional land form clear what is this oxbow le and here this thing which is happening in this way which river This river is doing this in this way speak meandering This is called meandering of the river so what is muddering so muddering is When our river runs in the shape of a snake when the river flows like this It moves in a circular motion like this Mudring says why does it happen like this because it's in a flat plane right now what is it now is in a flat plane and in that

39:10 There is too much debris so it will go like this It will do it only because it doesn't have speed that it can walk in a straight line and When it moves around like this, understand here When they roam around like this river okay the walking started like this It started, it started moving, then more wandered more and wandered more and wandered more she spun and spun more and when she spun like this then You will get this, you will get both these parts You see, when these meet then the river which She won't go back from there anymore it will flow directly from here okay why is that It will rotate straight now it will flow directly This part should be cut off from here This whole murdering would have happened, I would have told this to him Oxbow But this is also a kind of depositional land. It is the form which is formed in which stage

39:57 Mostly it is formed in the old stage at some places It will also be seen in the mature stage Because the muddering of the river is mature stage and the old stage If it lasts till then Oxbow is in the old stage only Lakes become like a graveyard in Bihar The lake is called Kabar Tal by the name of Tal taal article so this grave taal is yours Oxbow is an article and one of the Asia's Largest Oxbow article considered When the river comes finally all the debris goes away Keep all your deposits in one place If it collects something then it becomes like this triangular It gathers into a shape, this is called Delta of the river or the river If the mouth is fine then the river is completely on its mouth Delta collects it and what is this is the depositional land form which is its

40:42 If it is formed in the old stage then youth full stage There were dominating erosional features such as Your V Shaped Valley Gorgeous Canyons Waterfall Entrenched Munder Entrenched Munder What is the difference between meandering and normal meandering Brother, this is how Ant Mander is working what is that where your in the mountains i.e right up there where it originates There, if it is cut down to the mountains As she is moving around, a shape is formed in the mountains This is what we are going to say about this very thing Looks like an entrenched mand ring anyway The chat in meandering is in the old stage but The entrenched muddering which is this youth full stage I start seeing this river terraces because just like when the river flows So this is how this land form is created It is called river terraces pot hole plug pulse what are these erosion land forms there if we talk about

41:29 Elvil Fan Became Levi's We got to see all this in Oxford Found under Deposition Land Forms And these are mostly made like delta If we talk and Oxps are made on top like this right because from where the river immediately When the water comes down all the debris gets collected here I did it, this is called Elvil Fan now You will see the land that is created because of the glacier Which lands are the forms created? There is no doubt even hain malwa means mud yes it is mud n million There are going to be faces reveal plague lake is not called it plague pool they speak

42:14 usko malwa in english malwa in english They say that you don't see mud here, mud mud happens it's ok Delta Vs Ishwari Abhinav Mishra This is me I will teach you about reverse I will teach you, for now just understand that it is delta it is like debris has collected so we have collected it like debris You will read this when you read the river system then If you would have read it then Narmada has become Tapi which flowed towards our waste Those rivers are divine tides, the reason for this is that the first thing So if it flows in the rift then that much More silt like what is this debris silt OK, so it doesn't take the silt with it because the rift volume is flowing and It's okay if it takes a little bit because the cost is so high here Is

42:59 na coast which is the western coast it's so It is more mutter that here proper The site of deposition cannot be found It would have completely vanished in the river right here if it is there then we don't see the proper delta Somewhere in that same land form is called Eastory It is said here what is here Because the Eastern Coastal Plain is our wide It is easily deposited properly delta and because it is very long Big rivers come towards the east Towards the east it forms a delta here That and the one that flows into the waste is Pachori Now when we come to the glacier, we have glaciers like the glaciers from here It must have started to walk, so look, it has moved So look what kind of shape is there here be created I went here and saw how it happened here It is not vertical, your ridge type has become like this na can you tell Addys that you created this Gaya then what is this, this is also a geographical feature

43:46 This too has become a shape, so they don't care give some names of glaciers if I If I talk about it then they have a lot of mass These glaciers are very heavy So what do glaciers do when they move? If we start from where this land is The form was created which you can see here this is the thing okay this one which this is a thing we call it sarcasm how we will remember what they did by moving slowly I have created it, Sark, I have created it, Sark Sark will come here slidingly slidingly These too will come here slowly, these too If you come here then this is the middle I do it like this with an elevated part bun will go to whom we are addies in hindi ok If it is spoken in normal language then it is called By the way we give the term Erie What is called Arite or Sired Ridge speaking is known as Sired Ridge because

44:35 Clear, clear and here it is absolutely top It has a very high top which is called a horn So by moving around it became a Sired Ridge or what is arit and hon ye turn This is a type of article like this one here somehow a pit has been created here if When the water gets filled then it is called a turn lake okay so now a glacier came from here The glacier must have come from here The glacier must have come from here The glacier All the glaciers must have come from here If you have found it here then there are many here A lot of debris must be flowing A large glacier mass flow must be taking place Because of which a valley will be formed here. shaped like a u shaped valley bun will go and it will become hanging wala Why because the glacier that is moving here it must be of very high mass as compare

45:20 to these small valleys that have been created The small valley that was created came from here So small glaciers come from here I was coming here and suddenly I got everyone so it was big If it is made then it is a yes because it is more what will it do from below more here than below Below will exhibit more erosion The one below will get more scratched like this Understand it, down to that depth If you go, it will look like this that these latex have been these valleys up there so That's why they call it Hanging Valley Which main valley is this? This is a U shaped valley. So if we look at erosion land forms If we talk about Glacier then Erosion Land What will come in form, one is our road Sark became Sark and what was made of it areator ridge same fine sired Ridge horn made

46:06 it was okay what is this erosion now what will happen to the deposit when it comes from here Okay, what will the glacier do if it comes? deposit a lot of things with you He will come taking it and when he comes taking it then Inside, that is, beneath the glacier By doing this things will get deposited okay In this way, the deposits will be done line by line We call them Escar ok remember this risk of resentment Gradually, the glacier which is getting inside There is water deep inside, deep down there is risk he made an askr okay then if we talk if we do it like this then here if we suddenly What is deposited by the glacier? Because of this, more money will be deposited and more will be deposited If there is deposit then such drum line Make a shape of shaped or oval shape goes what we call

46:52 Drumlin what kind of shape is it oval shaped it happens like this line by line Assume a small deposit is being made What happened inside the glacier that this thing Some more has been deposited and some more will be deposited If some more things are deposited then it will look like this This entire land form will be formed which Drumlins are oval shaped and Moraines occur Wash Us In And Out planes okay out wash planes and if If you need a trick then remember it like this Brother, they are people from Morena, it is a place like Morena If it is in Uttar Pradesh then the people there are in love Standing on a plane, he is playing drums like this after doing it okay then out wash planed If there are moraines then what are moraines which are formed on the side due to deposition yes we call them moraines clear glacier erosion cirque araite

47:42 Eschs due to pitted ridge and hone deposition drumlin muren and outwash plain if ever If you ask me what this Jord is, it would be What will happen when the glacier passes us by So if there is sea anywhere nearby then if sea water will enter its valley or Then let's assume that there is a pit somewhere This is how the valley was created If a crater is created there then the ocean The water gets filled, the sea water gets filled It is called Jordan Sea Water Entering into glacial valley just think like this okay This is called fjord where the sea is It's sea water that entered the valley It is created somewhere in the pit like this Enter the Rozan Land Form done in it. It is called root, now we come to ground The land forms created by

48:28 Ground water is what is inside the ground The water that flows slowly is on the sea whosesoever he is inside, what is from inside Gradually the rock becomes weak It remains ok tell me which type of rock You get to see fossils in Abhay It happens like you might have seen somewhere But the soil collapses, have you heard that the soil collapses? When does Yajli occur when there is too much rain Then our soil becomes sandy why does it go down and sink because When it rained the water went down and when the water is gone okay so because of that he what did you do here it weakened him a little because of which the soil would collapse or sometimes it happens that the water He went inside and he cut this many parts completely I emptied it and got it right here.

49:14 if it is there then what will happen because of that if this thing If she collex then it will be too much These things will sink just like that let me tell you what sink holes what do you say Let's call them sink holes Just like the sink hole you create here sink hole this sink hole if I started meeting you like this, I met you like this I got this from here so it's a big long one like this A small hole will be created, long holes will be created these are called las sink hole or dline sink hole and If the dline is almost similar then If they start meeting each other, then this is Lapiz and limestone make Valas what are the pavements so look at the created by ground water These are the land forms there for you to see Wherever there is a lot of rock, we can find it it is soft the rock is quite soft and

50:02 Which rock is soft then limestone It's very soft, what would a rock be like it's sedimentary which is what I just asked you about In which rock could fossils be seen? if there are fossils then there is sedimentary rock limestone and dolomite rock have become these What is there in the rock, this rock is so much It is soft because when it sinks in water it is in that water This is the landform that is formed up here Now I have not put it there like this, if you

50:56 what starts to happen starts to dissolve So this is how lapis is made and when there are many Area in the same wide extensive area A lot of such lapis are made in Now we call it limestone pavement This water that is down will seep into anything He has broken everything I said, he has mixed it up take him in What will happen to limestone and dolomite? what have you mixed enough of, so take this thing inside It will go and when it is taken inside, it will happen slowly what is this with the water that drips down the part will drop down stand like this It will go in tower shape, it will be called stalag The mite that drips c t i t e s t e l and how will you remember the stalagmite below if It would take time to forget you if you could So who is hanging from the ceiling up there? So how will you remember that these top

51:42 If it is hanging from the If you don't hold it tight, then you will be affected by gravity Will fall into the influx and the stalag mite which is rising from below, from the ground now Sometimes it happens that both meet What will happen to both of them together? will go when both of them meet So it will have a structure like this They say pillar, if it is ok then this pillar stalagmites stalagmites and pillars what is this Sink holes formed due to deposits Dline Lapis Uva and Limestone Pavement are formed due to erosion now comes the C through the waves that flow through our sea waves are created by him What are these land forms? these are yours, these are our seas if there are waves then why do the waves move We will study what causes waves. Firstly brother, the wind is blowing, so the wind

52:28 The wave can move because of the fine wind because of this wave can move because of wave tide Is it possible to work or not because of the tide Waves can come due to tsunami also But it could be a very dangerous wave. This would have been a very scary wave It is very rare that an earthquake causes a tsunami When does a tsunami occur and what does it mean Its tsunami comes only when there is an earthquake When the hypo center is inside the ocean and This is a Japanese term meaning harbor. If waves happen then waves come because of things Now what happens when the waves come It is normal, if we understand it, it is very basic leave it clip flip what is written brother If the waves move like this then this sand It deposits sand here they do it and what happens because of it is it because of this that our middle becomes

53:13 it becomes the middle becomes right here Let's assume there is a rock in the sea If the waves blow then what will happen to this rock? break the rock from all sides and The rock will become a steep rock like this It will become a steep rock, we should call it a stack yes let's say c stack okay now this It is good to understand C stack like this I have a C stack, I'll fill it up completely Let's do it like this, okay, let's say this is the C stack This is your complete C stack. Okay, now. what will happen to this and let's assume that what is in it and inside it now waves are blowing okay so what is that Its inside part is hollow and when hollowed out it will form an arch The shape will become something, it will become an arc shape this is called a sea arch this is called a sea When the inside of the arch becomes hollow

54:01 And just like this it forms an arch, it becomes a sea arch They say beach, so you already understand it is cliff What is this steep rock on the coast? You are looking at the rocks, they are called C Cliff calls them so now you understand Cliff What is stack, what is arch, what is kef what is a cave how is a cave formed so This is a cliff. If a wave comes in the cliff like this There was a slight depression and a wave started and A hole was created and when she moved, she went deeper and deeper If water goes in it becomes hollow because of that A cave is formed inside there and then there You can relax by visiting the cave in the middle of Goa you can study there, its ok So these are the benefits of caves Due to erosion the cliff became a steep rock The stack was formed and from its stem an arch was formed and The caves were formed right there, you understand the beach is sand what is dune what is here

54:48 sand dune is bar is barrier and On the spitter spitter is sea coast is connected to the coast If such a long deposit is made whose is this sand etc then we would call it if it is made of sand then it has sand spittle if if if if it is not directly attached If it is not directly attached then it it is said bar as if by doing it here like this Has such a sand been deposited? It is connected to the coast, so what will you say? we will call this bar what is this let me remove it here You might be able to see one thing here

55:33 what happened here a mean lagoon A lagoon has been created, or is it a sea, brother? edges are formed but are separated it is separated from something They just say barrier, this barrier is still there There is a sea in the middle of this lake There is a barrier between the lake and the sea When I say it, I understood the bars as well as the barriers I understood spit, I also understood what spit is is like this is coastal sand dune Attached to this, if you assume this type of dune if it is there then we give it spittle for this I mean this is the coast, okay, it's the coast, it's near the coast The edge became so separate that tell him again we give it separately like ours are square And if we assume that there is a lake, by doing this someone is fine and there's a sea here so in the middle of it The part which is there is called barrier and normally the deuces are created

56:20 Because of sand he got sand deuce and all this Because of the deposition that comes last Which land forms are affected due to this wind? are made because of the wind so because of the wind The land forms which are formed we call them aliens also known as land forms and These land forms which are formed are mostly It is made in deserts because it is made in deserts what happens is that most very few people live in the desert and when there is less in the desert If people live there then the wind speed is also very high It is too much, okay, why is the speed so high there like we have seen in Neptune in we read that it is the windist The planet is the windiest planet because We don't get much relief there If the features are not visible then the air The speed which is there is kinetic energy if there is too much of wind There is a lot of kinetic energy in the desert and there is a lot of sand too

57:06 Because of which sand will be lifted from one place If that wind is deposited somewhere then it will be The land forms of wind are mostly found in deserts such as like a this is a rock okay now what it seems like the wind is blowing very hard In the desert, the wind that is blowing in the desert if it is too much then its lower part whatever it is it will make it hollow in this way and This is how a rock shape is formed here We call this mushroom rock in a different way that rock is formed it is not only mushroom rock This is how mushroom rock becomes pedestrian Rocks got formed and more of our land forms would be formed it is like it is made by doing a combination, okay Jugan etc will not be asked in SSC But CDS asks you about this Etc. so Jugan this type of land form makes it look like something like this is okay

57:51 means a long land form is long If the rock becomes erect then it will be called a fire They say what is this, this is mushroom rock Mushroom Rock has asked this in CGL here the planes which are created, such planes which These are created, they are called Pedi Plane Keep in mind that penny planes are a different thing Penny plane is made because of water i.e. The planes that are created due to river water If yes, then we will remember him with water, Penny palen this is pedi palen and what are they and One thing to keep in mind is that it was raised in this, written here Pay attention to what is written and what is not written Your palayas are also made, what are palayas They are, I will tell you I am only in desert areas when the wind is very strong If she moves she will pick up soil from somewhere If she deposits it somewhere then from where will she pick it up A slight depression is created there A small pit will be created

58:36 When a small pit seems to be created here because of this some water will get filled then it Palaya says Palaya is ok and deposit What would happen if you saw it in the desert It is something like this, what happens is this deposit The sand which becomes so light while standing This is the slightly raised part isn't it? These are loosely called sand Deuce And these get created, they are called Birchen and Seif when the wind blows hard sand which is some soil which is something like this it deposits itself from this it is called are words or bars, whichever it is and if it has a wig It means understand it like this, not like this, Thakur's one The hand is missing, so is one of its wings it is missing one of its wings is missing Let's call it Seif then Birchan and Seif The only difference is that in both

59:22 This is done in such a way and a hand is used in this If it is missing then just call it that Birchan and Seif are clear then the lecture is Our short lecture ended here. We will ask questions based on this topic A little bit I mean I need to look into it a little bit Do not take too much load on this topic Slowly and gradually I did my best to explain I have tried to tell you as much as possible about So That I don't need to tell you too many things by heart Let me explain it to you here and a little more You'll have to put in an effort from your side, come on Ask the first question which of the following is the scientific discipline concerned with the description and classification of the Earth's Topographic Features sir please recorded classes of parama 3.2a The video quality is 1080p Do it ok Chandrashekhar right now in this lecture So I can't say anything because maybe I also need to do some settings etc on some laptops.

1:00:09 probably will have to na what is the difference between hanging Valley and Canes Snigdha Deep Choudhary Watch The canyons that form in the Hanging Valley I taught you everything is fine in the glacier Soon everyone will do this second and third too we will question those whose case has happened, it is okay We will ask the second and third questions and one more thing I have to tell you right now, it is an important thing I will tell Oasis is asking Shavita Sharma oasis is that part where Grow some vegetation in the desert A part in the desert where there is little Vegetation plants can grow like this Well they say that whatever is formed is a canyon Canon Grand is formed due to river water the canyon is the largest canyon okay

1:00:54 The Hanging Valley in the US That glacier is formed because of the glacier land form then in canyons and gorges if If you ask me the difference, it's much better It remains as I told you Well first of all if we talk about it here then it is jiyo jiyo one second Mofolactic feature of a desert landscape So what are your desserts made of? Birchan and Deuce will form a U Shaped Valley in Glacier will form I will make this river water in your river Because of this mishandling of river water also happens Because of this the third question is now the focus Understand that dash planes are formed due to the Weathering of Soluble Rock Such Edge Limestone and dolomite so limestone and dolomite which there are rocks there are soft rocks

1:01:40 Which land forms are formed in these sir This cannot be a glacier in the desert Even in deserts, vent gases are not produced These are made and are called Cars Topography keep one thing in mind here Note it down, you will find it in the notes that these are our ground water land forms We call these cast topography You might have noticed it written here as well it will be here if you notice carefully If yes, then the caste was also written here why is topography called cast topography ground water land forms We say this because the ground water Land Forms this is a karst region we find near the mediterranean sea near the mediterranean sea There is a region in Southern Europe It falls in what is called caste region there The rocks there are mostly dolomite and it is made of limestone so there it is profoundly seen therefore that
