Sir can you complete the series of GC Leong 🙏🙏please sir,your way of explaining is awesome,directly fit into mind ❤️❤️❤️ please please sir
I really enjoyed your explanation
It help me to understand better.
I’m a student at the university of The Gambia 🇬🇲 studying Geography
warm water remains on surface so has less salt. Cold water sinks to the bottom which matches with high density property, so cold water has more salinity than warm water.
Amazing way of explanation sir... the best teacher you are...thank you very much sir
It's just because of you i have started loving geography sir .Earlier i had a geographobia.Thank You so much.
is that even a real thing? 😂😂
Love your voice and the way of teaching.....thankyou.....🙂
Amazing lecture....
Please come back with 2018 upsc prelims analysis...
Thanks for your dedication
I think salinity of warm water is more than cold water because cold water not vaporise fastly than warm so water molecules of cold water will not vaporise and salt molecule of water does not comes on surface
❤️ Ur Explanation Sir and Thanks For this Wonderful lecture 💫 🙏
Thanks sir ... lots of love from ladakh ❤
Ocean currents made easy! I enjoyed your video.
Thanks alot you don't even know how much of a help youve been 🤘🏽❤😊
Love to hear ur voice after a long time.Sir pls start news editorial analysis.
thank you so very much sir..
very helpful your videos for upsc aspirants
Tq sir for ur shape and clear explanation 🤝🤝👍💗💖
Great videos for students thank you amit sir
Waah. Great sir. We always eager to watch your video and watching your video immediate after uploading. Best of the Best... !! thank you for blessing us !!
ur voice😍..i lv how calmly u speak..i want this in me
If possible, please increase the frequency of uploading the videos. They are too good. Information given is also precise. Appreciate your efforts. Thank you
We Appreciate Your Work. Keep it Up.
Best ho aap .... All doubts cleared..Tysm
great to see you again with yet another imp. video
Thank you so much Sir..
Clear and on point ❤️
Sir please do regular videos..!!
It fells that we got mesmerised with your explanation
Sir my only suggestion is that you should go in little detail also
i hv watched almost all videos of yours...few minutes back i was watching..modern history😁...plzz make more videos on history..i want to hear from u..what happened after 1857😁
Thanks for coming back sir
Universal teacher 🇮🇳👍
sir plzz upload chapter 15 and 16 also asap. we are waiting eagerly.
Nice and very exact to the point. 👍👍
Thanx Sir
Your videos are very helpful.
Thank you
Thank you
😀
For me Geography means Sir Amit sengupta's videos
U r ultimate sir seriously
Thank you so much sir 🙏❤❤🙏
Thank you so much sir....🙏🏻😊🙏🏻
Thank you so much sir🙏😊🙏
You're great sir... Thnkuu
Hi Amit,
Really glad to see you back 😊😊😊
Outstanding sir
Very nicely and clearly explained by you sir ...
Only 1 doubt how the occean water moves if it is writtern that the occean water do not flows like river ...
Ocean currents are like large rivers flowing in the oceans
Thank u sir 😊
Love ur voice ....sir
sir if possible try to cover GC Loeng and other important reference books of geography,it would be ur most kindness
Sir, please please please make some videos covering Theories in Geography as per UPSC Syllabus.
Thank you sir it is very helpful
Thnx❤
plz have look on my comments sir this is actual upsc sylabus topics paperwie made videos on they we r great full to u if u do so as u make very vell
Great teacher
Thank u
Very nice Sir. Plz also make videos on history
SIR IT IS(CORIOLIS FORCE )COUNTERCLOCKWISE IN NORTHERN HEMISPHERE AND CLOCKWISE IN SOUTHERN HEMISPHERE...CORRECT ME IF I AM WRONG....BY THE WAY UR EXPLANATION IS AWESOME....VERY HELPFUL...THANK YOU SOOOO MUCH
Exactly
No coriolis force is clockwise in the Northern hemisphere and anti clockwise in the Southern hemisphere
Coriolis force itself isn't moving in any direction. It's just a force which appears because of the rotation of the earth. Now this force deflects everything (including winds, ocean currents and even a freely falling body) to the right in the northern hemisphere, while the same force deflects everything to the left in the southern hemisphere.
Now if an ocean current is moving in any direction in the northern hemisphere, it will get deflected to the right, and this force does not act only once or only if something moves in a particular direction, the force acts continuously on the ocean currents because the earth is rotating continuously. So an ocean current gets deflected towards right continuously and this results in a clockwise direction in the northern hemisphere and anticlockwise direction in the southern hemisphere. I hope you have understood the point. :)
Thnx
THANK IU SO MUCH
Thaxx sir
Sir plz make available your notes link in discription
voice osam sir🔥🙏🏼
Sir please cover gc leong 🙏🙏
Kamaal ho sir ji aap
loved your teaching sir but you didn't included gravitational pull of sun and moon
That causes tides
thank sir
Please upload Ur videos on chap14, 15 & 16 sir.....asap
Please make videos on indian people and economy. Have more questions from it in civil service exams.
I will look into it.
Sir please start making vedios on laxmikanth indian polity
warm water contains low saline but when evaporation occurs in warm water then it becomes high saline. How? please explain it, Sir
How is cold water more saline, when hot water can hold more salt ?
I could not find similar explanation elsewhere!
Where is ur video on tropical andextra tropical cyclones sir???
Dear Sir...pls can you explain how cold water have high salinity and warm water have low salinity?
Do you still need it's answer?
Sir plz complete as soon as 11 &12 std
Sir please make indian economics
How cold water is more saline if the evaporation is less in cold water resulting less salinity?
Sir plz keep up d good work.
Thanks :)
Sir rivive your class 11 world physical geography series please
Does coriolis force also work on aeroplanes, missiles?
yes, yes it does

............................THANK YOU🙋😊🙋😊

sir when the next chapters are coming
Sir u said dense water have more salinity in chapter 13 of ncert class.....But the water in poles have less salinity is what i understood...But if cold water is dense then accordingly the cold water should have high salinity???
Water can be dense due to low temperature or due to high salinity,
in the polar region water is dense due to low temperature
Sir,,,if temperature increases eveparation increases so if evaporation increases, salinity increase right sir,,
The. How can salinity less in more temperature zone.
Salinity is directly proportional to temperature so temperature inc. salinity inc.
Ocean water moves clockwise in northern hemisphere not solely because of coriolis force. All factors determines rotation direction. So don’t get confused.
Why cold water current is more saline ?
❤
👌👌👌
Sir Cold Currents are Deep oceam currents or surface currents
Let me know
sir , what is the effect of temperature on salinity?
definitely it aids most of the evaporation and and leave behind the saline in crystal forms which we normally call as salts of the oceans.
Cool water has more salinity than warm water.
sir i really miss you don't y you so busy ?
Me: Binge watching all of the ocean current, water salinity etc videos because I have a science test
Me: **WATER IS WATER**
Isn't hot water more dense
But where is lecture on tidal movements,?? Importantce of tides
On its way!
Your voice
Why cold water is more saline???....if anyone know plzzzzzzzzzzzzz reply plzzzz
cold water is more saline because it's molecules contract and become dense, and, dense water is more saline because it sinks down
@@Me-mo6dt but it can also happen that warm water will evaporate faster and the water ascends as water vapour leaving behind salt....bt I'm not sure if I'm wrong then correct .e
@@CUINBOWL07 when the warm water will evaporate and form water vapors, so it does leave behind salt but it only leaves behind as much salt as it contained before. There won't be any excess salt left behind
Ok thankyou so much bt one ques how dense water automatically become saline(you said in the first comment)
@@CUINBOWL07 deposition from rivers and all water bodies that flows into it.They bring along the minerals and nutrients from the landmasses
Why ocean water salt?
Because river carries salt constitutents
MISTAKE
warmer water can hold more salt than cold water; it HAS higher salinity.
When the water molecules of the ocean become heated, they expand. Extra space is created by this expansion into which salt and other molecules (e.g., calcium) can fit. Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity.
