Very true
Incredible ...
Couldn't have thanked more for taking up this leviathan task and executing it the way it has been. That, too, so emphatically. Thank you, again, Amit Sir. You are a hero!
9:15 feldspar is found in all types of rocks ( igneous, metamorphic and sedimentary ). please do correct while watching .
this is one of the best videos. u xplained things so simply , infact the interesting part about the videos are those colorful pictures which doubles the advantage. thanx buddy.
Sir 1 doubt......u said lustre depends upon the crystal's colour......but sir....in the text its written that lustre refers to...."appearance of a material WITHOUT regard to colour"........sir kindly clear this dilemma
That was an error, lusture has nothing to do with colour.
Ye chutiya hai
Watching this in 2021 for the Revision purpose .
Presentation is too good 🔥
sir when can we expect the rest of the chapters from this book? eagerly waiting
Is a mineral made up of a single type of molecule....or is is mixture of molecules...I mean to ask that is it a pure substance with a definite chemical formula(is it a compound)
Is granite a rock or a mineral
Granite is rock...
Thank you so much for the detailed explanation of the complex concepts. I have one question. Does Limestone comes under mechanically, Organically, chemically formed sedimentary rocks?
It's a pleasure to watch your videos and learn about things with ease.
Thank you is not enough for you sir.
sir you say from @3:50 sec that lustre totally depends on its color, but in the book it is written that lustre is appearance of a material without regard to colour. plz clarify
Yupp I have the same doubt.
In the above slide it is mentioned that magma is the root cause for occurrence of minerals, so why or how do we find different minerals in earth crust ??? why dont we get same mineral everywhere ??? is der variations in magma composition ???
+Snigdha Singh Because it then reacts with other elements that are present in water, atmosphere and not to forget with right amount of temperature conditions various kind of mineral crystals are formed. And yes temperature variation is an important reason behind any chemical reaction. Increase in temperature increases reaction rate.
Snigdha Singh
Good question
Just Deposition of megma is not important for formation of minerals there are many reasons which affects the formation of rocks like slope, temperature, pressure, water, time etc.
Like take one example if plant and animal deposit at any place and after due to hear and pressure it convert in to coal again if the pressure and heat is increasing with time coal will convert into diamond due to metamorphism again due to more heat and pressure with time it convert in to new mineral from diamond... Like wise mineral is different
Sir your explanation is too good..
Thnx for explaining..
Indeed
Dear Sir,
❤️ Ur Explanation, Animation, Pictures that u included and Thanks For this Wonderful lecture 💫 🙏❤️

Sir ur explaination is superb...please complete the remaining chapters also..Thankyou:-)
Thank you so much sir for clearing our concept so perfectly..🙏
Indeed
one question about dynamic morphism: suppose this is a rock : ● ,now if i break it into 4 chunks i get four pieces: • • • •
now my question is : does my breaking of this rock change their molecular arrangement? if yes then can this be called dynamic metamorphism? (i.e simply breaking a rock)
if no. kindly xplain . pls
+udita Raw Look the important aspects of metamorphism is extreme heat and pressure. That's what changes the shape and structure of a rock. But simply applying force enough to break it doesn't mean you changed the molecular structure. You basically broke the rock Into 4 parts, the molecules are separated. Now those individual parts are separate rocks with a structure different from original form.
Amit Sengupta yes and its like if i have a big green saree, and if i chop it 20 percent, that doesnt changes the fibres/ textile ( molecular structure in this case) of the saree.
Amit Sengupta thanks
Thanks a ton sir. Your voice and explanation beats most of the channels
sir you are great
and sir hindi Mai bhi translate Kiya karo kuch lines jldi Nikal jaati h or kuch word hard hote h..
Ahan Shrestha ek baar pause karke padhlo sunanese pahle fir Samantha ayega😀
Commendable presentation,explanation was top notch 👏
Love ur voice too 😊
One doubt sir...on convergent process smaller plate go below or large plate go below
Smaller plate... Especially the plate which has less dense
I like it 👍❤️👍
Sir your explanation style is very great. ....And help me more for understanding in depth..
Please make more videos...Of other subjects of ncert and references .
Grains are large inside the earth's crust because of slow cooling rate and above the earth's crust cooling rate is faster due to wind and water vapours hence results in a fine grain structure. This is a core concept of all cooling and solidification process. Mechanical engineering students might understand it easily. 👍
Your video is informative. Thank you very much sir 🙏
It's been 5 years you've uploaded this video but I really wanna appreciate the content ,explanation and the hard work of you for helping infinite folks who are unable to find good sources to understand geography .To cut the story short even I also struggled a lot to find good geog. content .Huge respect Sir @Amitsen gupta❤

Sir u haven't told major minerals and their characteristics...plz u can...sir
thanks sir .videos are very helpful.
please upload 6th chapter GEOMORPHIC PROCESS and remaining chapters as soon as possible.
Thank you sir, aisa lagta hi mai apka video 1.5 ki speed pr dekh rha hu
My only question is how they appear on earth surface if sedimentary and metamorphic rocks are formed deep inside earth crust...... ❓
Amazed everytime i watch this❤️
i love it just heartfelt thanks to u sir
Can i get your number
EXCELLENT PRESENTATION BENGALI SIR...EASY TO UNDERSTAND AND VERY PRECISE..THANKS
Thank you sir. In this video I have cleared my all doubt's
Sir, Ur way of teaching is very unique and best
sedimentary rocks also have these visible line (19:55) . So what's the difference between foliated metamorphic rock and sedimentary rock?

You are the master of Geography...
Thank you very much sir I have cleared doubts sir please make history book chapters of class XI ncert
@ 3.50 lustre depends on colour but according to book it's independent of colour..Please clarify
one question please : its written in the book , the first page of this chapter 5 says *mineral is an INORGANIC substance* .......... *then why* on the same page *coal, petroleum and gas* are considered *organic minerals* . ain't these 2 contradictory statements????
+udita Raw coal, petroleum, gas all these are organic because they are compounds basically made of more than one components like decay of dead plants and animals, then various kinds of acids produced during biological weathering, that's why they are organic. But minerals are extracted from rocks. And rocks are either igneous, metamorphic or sedimentary. And we know igneous is the first step of any rock. And igneous is solidified lava. And that makes it inorganic.
Amit Sengupta yes thats d differentitaion that u just gave. i know coal , petrol , gas are organic in nature.......
but my question is why the book called the coal,petroleum ,gas *as minerals* ? coal is not a mineral , neither is petroleum and gas. then y its calling it an *organic mineral* ?
as the first page of this very chapter mentioned *"minerals such as coal, petroleum, gas"*
so why refeering them *minerals* ? despite knowing the property of a minearl.
+udita Raw 2005 printed book, more than a decade old. Errors exist! :)
Amit Sengupta thanku so much,though i have the oldest ones... anyway.... oh yes any video for history optional??? i mean just a basic one,.. how to start.. ?
+udita Raw I have a video on modern history crash course from 1600 - 1857. May be you want to check it out!
Really all your videos helped me a lot... Thank you
Very simple to understand
Sir amazing video, Question: So, If all the Volcanoes becomes dormant would there be no rocks formation? Just a thought?
+sagitait Riddhi Rocks are formed due to magma. So even if you close the volcanoes or they become dormant, magma flows inside the crust as well, that won't stop. That's why when you dig more in depth you will find rocks.
Amit Sengupta sir in text book luster- appearance of a material without regard to colour but u said because of colour at 3:59
Sir please complete a video on intrusive volcanic landforms.
Nice lesson. But too many ad in between..
Can't complain though.
Thank u.
great sir. plese make entire syllabus of geography for upsc sir.
Sir very nice coverage of this chapter ...every portion is covered with clear and detailed information. ...thank you sir very much for making geography easy and interesting for me..keep making videos on different chapters and topic ..
Sir your way of teaching is awesome 👍
Thank you for such nice videos.
This chapter looks easy but was giving me a tough time. I thank you from bottom of my heart.
Thank you 🙏🏼 Sir ✨

Thank you sir for these videos. These are helping me a lot in preparation for the entrance exams. You are an amazing teacher.. 😊😊
THANK YOU
It's amazing video👍
3:55 Lustre doesn't depend on the colour of the mineral. A mineral can be extremly black but glossy while a white mineral can be extremely dull.
Sir thank you for uploading these videos.. Help us a lot 🙏
Great explanation❤❤
sir please complete rest of the chapters soon..its my humble request.
Amit sir if possible please show the link in your description box of your notes and if you can make some sample papers for GEO class 12th 2022 then please do so!! Videos are nice but postulation warily work upon it.
Thanks
No one can explain as good as u do sir
