Hey, great videos. But just wanted to point out a small error that is being continuously repeated over the videos.
So when two tectonic plates of different density/weight collide, the one that is denser or heavier usually subduct's beneath the other. This typically occurs when an oceanic plate collides with a continental plate or another oceanic plate. The denser oceanic plate will usually be forced beneath the less dense continental plate, or in the case of two oceanic plates, the older and colder plate will subduct beneath the younger and warmer one. In case of both continental plates, neither plate is significantly denser or heavier than the other, so subduction typically doesn't occur. Instead, both plates are usually pushed upwards, forming large mountain ranges. The collision results in intense geological activity, such as folding, faulting, and uplifting of the Earth's crust (this is what resulted to what we today called The Himalayas).
Yes, you are correct.
Himalaya formation is from sediments of tethys sea as indian plate is heavier than eurasian plate it slipped below the eurasian plate
14:00 Contents of the chemical weathering process are removed from the new book
16:50 Physical Weathering.
I am preparing for UPSC. After going through the chapter twice, I go through these videos. Helps me to solidify concepts.
👍🏻👍🏻
What's your Optional?
This message was 3 years ago .. wht about your career?
I wish I had a teacher like you...love your conceptual understanding sir.
I was trying harder to understand this chapter than i found this video and now my concepts are very clear 👍🏼
Wonderfully explained! Specially the way the video is edited, putting in appropriate videos and diagrams in the box. Dil se thank you for all your effort.
Everytime i face any doubt. I just go through these videos made by amit sengupta. I think he is the best we all can have , he charges no money for it, so guys buckle down.
well, dont forget the ad revenue !! lol
@@memelord7551 but that doesn't count as we are not giving money directly
Yes me to everytime when I get doubt I think only amit sengupta .
I will just say .....SALUTE to you for this intiative...really very simply explained videos.
Sir,I request you to make videos of other subjects as well,please.
Watching the videos 3 yrs after it uploaded.. Still so relevant.. One can't find the other better way to read geography.. I don't even feel the need to read the ncert as u covered everything which even can't be found in ncert.. Thnx again sir.. If possible plz take up other subjects as well.
Lots of content is missing in new NCERT.
Yeah
Yeah !! I was checking my book again nd again ..haha lol
My new ncert same problem
Yeah , I too was wondered .... I was getting many points Missing .... Many times I checked the number written on page if as page is missing ... Many graphs and tables are also Missing in new NCERT 😑
Same...
I don't even need to open my book, your video is enough 😊 Thank you
Dear Sir, I find your videos very useful and impactful, It's always a treat watching them, I would request you to make the same kind videos for G.C Leong Geography Book as well. It would be of a very very Great Help.

Salute to the legend😊😊😊😊
Useful information. Students will love the presentation .Great job!
Is it required to study the eliminated parts like chemical weathering and physical weathering?
Is the deleted part relevant now? As the video is 6 yrs old
Your voice...is just awesome !
Great video! Wonderfully explained. Thank you so much.
I wanted to highlight one issue about the present edition of class XI physical geography book (might be helpful for those studying for exams presently)- I guess due to the COVID-19 pandemic, there has been rationing of the topics in the textbook, which has led to several abrupt rise of topics within a chapter and lack of flow from one topic to another. For example, under mass movement, the textbook only has landslide now, whereas in the earlier edition of textbook we had rapid and slow movement (which we see in the above video). If you pay attention to MCQ in the post-chapter exercise section, rapid and slow movement is mentioned even though it is absent in the main text. Also, few figures like figure 6.1 is missing from the present edition but the in-text mention of (Figure 6.1) is mentioned. Very badly done editing by NCERT. In this context, the above video was certainly a blessing.
thank you so much sir for your efforts. the way you explain is unique. here I would also like to mention your history lesson where you have explained using a timeline. through that method for the first time history made sense to me. can you kindly do the same for 1857 till freedom struggle. that would be really helpful.
Plz share the link of that lesson dear😊🙏
a great help thank you for bringing to us

U r just perfect sir.. u have truly explaining like a story... which made it really interesting... thanks from the bottom of mmy heart
i like this kind of teaching...line to line,,,,,word to word,....
sir ek no. padhate ho app very mza aa gya mujhe lga tha ye physical geography mujhe bn hi nahi sakti and lukily app ka recomendation mil gya aur you made impossible possible mujhe sab smjh aa gya jitna apne padhaya
6:18 Not smaller plate goes under bigger ....the fact is bigger plate goes under smaller plate because of high weight....
Not bigger but denser plate.
@@mohdfaizan1126more denser got subducted under denser one.
@@tbfyouthtalks1812 right bro
Usually denser part goes under. But if same density plates collide then bigger plate goes under the smaller plate
Oceanic plate undergo subduction due to its higher density then continental plate
Thank you so much sir. ...🙏🏻😊🔥
the small clips in between make things more understandable...Thank you so much sir for your efforts...
