At 20:49.. It is the heavier plate that subsides not the lighter plate.. (Note: Oceanic plate is made of basalt and is heavier than the Continental plate which is made of Granite) In convergent plate tectonics, we have 3 cases : Case 1. Ocean Plate- Continent plate convergence : Here the Oceanic plate being heavier subsides beneath the continental plate. The subducted part of the oceanic plate goes into the asthenosphere and due to high heat in the asthenosphere, the oceanic plate melts and its volume increases( density decreases), thereby due to high volume and low density, the magma comes out of the earth's crust from fissures forming island arcs. Trenches are also formed at the point(all along the oceanic and continential plate convergence) where oceanic plate subsides beneath the continental plate. Eg: The Nazca (and, to a lesser extent, Antarctic) plate subducting under the South American Plate, meanwhile, uplifted the Andes and peppered that towering range with volcanoes. Case 2. Oceanic plate- Oceanic plate convergence : Both plates being heavier ( made of basalt) will push each other, but the heaviest plate will subside forming island arcs and trenches as explained above. An example of an oceanic/oceanic convergent boundary is that between the Pacific and Mariana plates, which includes the Mariana Islands arc and a subduction zone encompassing the Mariana Trench, the deepest part of the World Ocean. Case 3: Continental plate- Continental plate convergence: As both plates being lighter( made of granite), none will subside. Both will push against each other, and as none subsides, they will result into fold mountains. ( Jab koi plate niche ni ja skti ek dusre ke against push karke, to common sense kehta hai wo upar ko fold hojayengi) eg: The classic example of a continental/continental convergent boundary is the rumpled overlap where the Indian Plate drives into the Eurasian Plate, a tectonic collision that has thrown up the greatest mountains in the world - the Himalayas - as well as the vast, high Tibetan Plateau. To the west, the Alps grew in similar fashion via the collision of the African and Eurasian plates. Mujhe clear ni hua tha amit bhai ka video dekh k ye topic so I had researched a lot and wrote all this so that i can help someone.. Do thank me 😛
First of all a great thanks to you, for making geography such a easy subject to understand. Sir you are doing a commendable work and reducing the reliance on Coaching centers. God bless you sir. commm
HONESTLY SIR, MANY A TIME I THING OR RATHER TALK TO MYSELF THAT HOW COME SOMEONE CAN PUT SO MUCH OF EFFORTS AND PAIN TO CLEAR EVEN THE THE MINUTE CONCEPT TO US WITHOUT TAKING ANYTHING IN RETURN. Sir you are like "SUN" which rises every morning , give light and prosperity to all without asking anything in return. Thanks a lot !
You made a commerce graduate understand these difficult aspects of physical geography. Thank you for your incomparable efforts. P.S. You have an amazing voice
I never thought learning Goegraphy could be this interesting. I always been hated Geography because I couldn't understand even a single topic during my elementary days. But now through your video I'm learning Geography with joy. Amazing speaking skill with illustration! Won't be able to thank you enough for your effort into every video you make. God bless you Sir and keep doing it!
Sir, the amount of thought and effort you put into these videos shine through in the quality of your content and the clarity it brings to your viewers. I felt geography was never my strong suit and after watching your videos, I feel confident in my grasping the concepts. Please accept my heartfelt gratitude and hope that you will keep the videos coming. :) Raashmi.
Wow! After one year of reading Geography from here And there.. Here comes a one stop solution to all the doubts faced by the students:) Thanks a lot sir for making such a brief and easy to understand video☺ Nd your Clear voice makes it more interesting!:)
Love Wegner....if it wasn't for thinking outside the box we would never go to next steps of theories. It explains the old kingdom's being buried. The man did his best before sonar. Now hopefully younger generations will explore
Thankful to the person who explained and made very beautiful and nice explanation. There is no disturbance in between no other talks like other materials available on u tube. This is best way of teaching, it makes me continue concentration and nicest to understand.
best explanation THE BEST EXPLANATION WONDERFUL ..... words fall short for your dedication and hardwork .... you are like a blessing to all UPSC ASPIRANTS.....
Sir, I just liked the way you explain and your voice so clear.. Though I just recently started watching your videos on geography... Iam too glad to see a such good explainer.. Keep going sir.. I have my exam tomorrow and iam absolutely sure that i'll achieve good marks.. Thank you so much sir 😇💙
👍Respected sir, U R A TRUE SAVANT...the efforts that u put in explaining each and every topic is praiseworthy💐💐💐😊..literally sir u just don't read the lines of the book but explains it in remarkable way . I am extremely grateful to you sir for adding pictures and animation as well for our better grasping power. 🙇🙇🙇
6:20, theory presented by Arthur Holmes is not rejecting the continental drift, but in contrast, supporting it by giving a rational reason of force that could have been generated by convectional current in upper mantle layer. Ratifying the error in that part.
sir i am very greatful to u for such a interactive lecture .This video is not less than a lifeline for my soon upcoming exams.once again thank u very much . please keep it up such nice initiative.
I was studying the chapter just a day before the examination, but still, after I started to watch the video all my queries were solved in no time. And also ended up scoring the highest in geography in all of the eleventh standards. Thank you😊
Sir i don't Know how to express my gratitude for u for this geography lessons. Was facing problem in this book. Ppl suggested to watch Mrunal vedios but i found the language of mixing Hindi n English quite problematic as im from NE India who is preparing from hometown n nvr been to Delhi. But trust me i found this vedio today itself n since afternoon I'm listening to u n it feels like geography has nvr been so easy. I'm so thankful. Will be revising Ur vedios till 2020 UPSC exam ends. I wish u all blessings of the world. You have no idea what a great contribution u r doing.
Amit sir you have done a remarkable job...one of the best ever explainations with illustrations...with due respect...but one mistake is there in Oceanic Trenches...deep Ocean trenches are are formed due to convergent boundaries..not by divergent plates.....basically..when two plates converge out of which heavier plate subduct into the lighter one...and when this happens Trenches forms. Thank you. UPSC 2019 mains qualified. Personality Test awaiting..

Awesome class sir. Being a science student I found it so so boring and difficult to understand this chapter. You made it so simple. And also you speak like a foreigner 🙂. Thank you sir
Althaf shameel As a student of science background i want to say , geography is a science. For a better understanding of Geography you have to clear your concept in science that made easy learn Geography quickly lipstick and example of rain for Rane you have to know what is evaporation conviction condensation so try to relate science and geography together you don't feel it bore anymore ☺️
Thank You very much sir for uploading the video today was my exam and a question came about describing the continental drift theory proposed by Alfred Wegner.In the morning today at around 2 o clock I saw your video and it helped me a lot.Once again Thank You very much.I will keep attending your classes from the next session.
20:49 In all types of convergence, the denser plate subducts, and the less dense plate is either up thrust or folded or both (upthrust and folded). 6:47 Trenches are formed in Convergent Boundaries/subduction zone.
A brilliant effort to simplify some very complex concepts of geography that too in a very short time. Keep up the good work ! Throughly enjoyed the tutorials sir :)
Sir u teach in such a good manner. It helps us alot. Just one correction is needed in this video, Trench formed when two place collide with each other not move apart. One plate subducted and another moves upwars there Trench is formed. It is also known as Expression of subduction. Source. Plate tectonic book of Condie. Rest video is 👌
Dear Sir Your video has everything which a student can ask for. The vast amount of knowledge you have is supreme. The only thing is which i want you to consider is that in some topics give a detailed explanation even if the video goes long because as a non geography student it is very difficult to understand these topics
