Who decided that naming two different things the mesosphere was a good idea?

Thanks, awesome summary of the earth layers!

[@randyblackwolf]

I have a quiz this morning, and this was a great visual aid for my Oceanography 201 class. Awesome video.

This need updating: -They have discovered in 2021 the Inner core is made of the 2 parts, solid inner most older with magnetism one way, and solid outer-inner younger with its magnetism about 90 degrees off. -Then the already , semi-known the liquid outer core which they think gives our magnetic field (which is getting turbulent causing the field to flip), -The known D boundary (really unknown, maybe crystalline), -The inner mantle (including the known large low shear velocity [hot] provinces under Africa and the Pacific Ocean, causing plumes like Hawaii and diamond tubes), and the outer mantle - all which which make up the mesosphere (maybe not all rigid), -The plastic asthenosphere, mostly rigid lithosphere and crust (including the various tectonic plates.)

Finally another person that knew this😂

[@siddharthdivekar1008]

Well, thanks for the info

[@CRISNCHIPS12398]

Very interesting! Thank you.

[@yayizhang431]

my science teacher really needs to watch this video.......

[@roadlesswandering]

I watched this entire segment of videos and this was a great way to end it. I really like the comparison between the chemical and mechanical layers of the earth!!!!

[@shouryaveersingh8000]

thanks khan you are the best👌👌👌👌👌👌

[@Ivoriana상아]

Who is disliking this? Ima find y’all. This help me learn UwU. And I enjoy this more than school UnU. :)

[@Shoyrou]

Nice quick explanation about the differentiation of the earth. Glad you fixed the part about the mantle! It is propperly explained now =) ty. Maybe you should make a video about convection cells explaining the tectonic movements. Nice work!

[@whateverrr1584]

Amazing explanation. I had a few confusions....but it sorted it all out!!!Thanks for this video!
