Found a big mistake here, the Salinity at Equator is quite high compared to poles, because lot of water her get evaporated, ofcourse it does rain, but the amount of evaporation is much greater hence it is more saline. And in case of polar regions , fresh ice from landmasses melt and reduces salinity. The highest salinity is found in water bodies where there is no rainfall, temp is high and no rivers , eg: Mediterranean sea, Dead sea, etc while r near tropical latitudes.

[@tapanshah8977]

+Kanishka Kani yup exactly...

[@dushyantsharma1126]

+Kanishka Kani Average salinity of ocean is ~37 %, and at equator it is ~35% and at poles it is ~32%. So with respect to average salinity of the oceans, salinity at equator is less due to influx of fresh water due to rainfall and high humidity.

[@RohitSharma-ko8gv]

[@dipdip458]

Kanishka Kani In Phase Transition When Water Solidifies Then It Does Not Incorporate Salt In The Ice Crystal(No. of Phase =1; I.e., ice crystal is PURE H2O)) Therefore the salt remains in the lower part of the ice sheet :-)

When sea ice forms, most of the salt is pushed into the ocean water below the ice, although some salt may become trapped in small pockets between ice crystals. Water below sea ice has a higher concentration of salt and is more dense than surrounding ocean water, and so it sinks. In this way, sea ice contributes to the ocean's global "conveyor-belt" circulation. Cold, dense, polar water sinks and moves along the ocean bottom toward the equator, while warm water from mid-depth to the surface travels from the equator toward the poles.

@ 21:37 , correct me if I'm wrong, but it should be pantagonian desert not Namibia desert. Except minor mistakes, who will give you this precious knowledge free, people complaining don't have value of this lessons. People also complaining about English/ Hindi language, the lessons are for whole Indian people not a certain part of india. They would have recorded all lessons in Gujarati if they want Bcz institution is Gujarati based, but they have recorded in Hinglish so value their efforts, we are not even doing what they've done for people. So just appreciate the efforts. Have any doubt google it. Write in comments section so that people watching can get the mistakes, but don't disrespect the efforts.

Contradicting information -- At 12:20 we denied the fact that the revolution of Earth does not influence ocean currents although we know seasonal variation are caused by revolution of Earth itself. And at 28:02, It is mentioned that seasonal variation leads to change in monsoon winds which further leads to change in ocean currents direction. So, that MCQ should again be looked into.

[@user-ko8nk7sq8x]

Thankyou so much mam .. great job

[@saurabhshukla9228]

There is constant motion in the ocean in the form of a global ocean conveyor belt. This motion is caused by a combination of thermohaline currents (thermo = temperature; haline = salinity) in the deep ocean and wind-driven currents on the surface. Cold, salty water is dense and sinks to the bottom of the ocean while warm water is less dense and remains on the surface. The ocean conveyor gets its “start” in the Norwegian Sea, where warm water from the Gulf Stream heats the atmosphere in the cold northern latitudes. This loss of heat to the atmosphere makes the water cooler and denser, causing it to sink to the bottom of the ocean. As more warm water is transported north, the cooler water sinks and moves south to make room for the incoming warm water. This cold bottom water flows south of the equator all the way down to Antarctica. Eventually, the cold bottom waters returns to the surface through mixing and wind-driven upwelling, continuing the conveyor belt that encircles the globe.

Ocean currents are generally slow, moving at a few centimeters per second or less. Deep ocean currents are even slower, moving at a velocity of several centimeters per second. Surface currents are 10-100 times faster than deep ocean currents

[@RoushanJ]

If equator is less saline because of the more rainfall. Equally, equator will be more saline because of the more temperature with respect to the other region. So, both are interdependent, saying equator is less saline, is not acceptable.

Hi everyone(Including Rajtanil mam and mrunal sir), I had gone through this video an year back and since that day,I have made this conclusion about Coriolis force that it moves in clockwise in northern hemisphere and anti-clockwise in southern hemisphere.Because of this,many of my questions got wrong whenever I attempted questions of coriolis force. So,please someone please help me out that in which direction does Coriolis force moves in northern and southern hemisphere ? Thanks in advance..

[@pavanjoshi169]

First things first - force does not move , it is applied on an object. Only particles and energy move (propogation of energy I mean) Now coming to coriolis force, the Coriolis force is an inertial force that acts on objects that are in motion relative to a rotating reference frame [ Here rotating frame = earth and objects in motion = air/water molecules ]. It deflects objects in motion in northern hemisphere(NH) to their right and those moving in southern hemisphere(SH) to their left. A continuous application of this force results in CHANGE in direction of motion of an object already in motion ( remember , it does not affect an object stationary relative to earth ) in either a clockwise direction (in NH) or an anti clockwise direction ( in SH). This results in winds and ocean currents getting deflected in the respective directions in both the hemispheres.

[@Bachpan565]

harry singh in northern hemisphere right n in southern hemisphere in left direction

[@vikasraturi4509]

harry singh let me clear you cyclones i.e winds around low pressure area in northern hemisphere moves anti-clockwise while ocean currents move in clockwise direction in northern hemisphere and also anti-cyclonic wind in northern hemisphere moves clockwise and mainly ocean currents are caused by these anti-cyclonic winds so ocean currents move in clockwise in northern hemisphere. Also opposite is true for southern hemisphere. Thanks

[@rupalirautela596]

I'll tell you a trick We know direction of current ≈ direction of wind So, direction of the wind , irrespective of its origin, always deflect towards their RIGHT in NORTHERN HEMISPHERE. While direction of wind , irrespective of their origin, always deflect towards their LEFT, in SOUTHERN HEMISPHERE. good luck 🤗

[@anshulsalsa]

Maverick Singh yaaa.u r correct...she explained it incorrectly....going by her explanation it would deflect to the left rather than to the right as shown in the slide...actually it would deflect to the right but reason is different....as missile moves north,to conserve its angular momentum its rotational speed increases than that of earth below it and it seems to go to right in north hemisphere...if you are science student u will know about this conservation of angular momentum thing..otherwise don't bother and just take my word for it....hope it helps...
