I understand that the continental crust is the thicker crust so it sticks out, but if it's much less dense than the oceanic crust, why does the continental crust sink into the lithosphere much more than the oceanic one? Shouldn't a denser material sink in more? I'm having trouble grasping that haha
+sebastian sartorialissimo The continental lithosphere rides atop the underlying asthenosphere because the continental lithosphere is less dense than the underlying asthenosphere. Oceanic lithosphere is also less dense than underlying asthenosphere. It is for that reason they both sit atop the asthenosphere. IF you had a chunk of oceanic lithosphere and the same thickness chunk of continental lithosphere, "floating" side by side in asthenosphere, then yes, the continental lithosphere would ride higher than the oceanic lithosphere (sink down less) because oceanic lithosphere is denser than continental lithosphere. Denser objects will float lower in the water.Objects that float displace their equivalent mass in the material in which they float. Denser materials (same volume) are the more massive, so displace more (sink lower). So in all that, you're correct. However, continental lithosphere is much thicker than oceanic lithosphere, and so even though less dense it is much much more massive. Thus it must displace a much larger portion of asthenosphere and sinks lower (as well as rising higher). I hope this helps. :)
Katryn Wiese It does help, Katryn! Thank you so much for taking the time to answer. I actually Googled you just to know what sort of professional background you have and I must say I'm honoured to have had an oceanography and geology Professor answer my question! Thank you very much! Greetings from Mexico City. =)

Thank you! This was a much better explanation than my textbook. And this didn't cost me 150$!
Thank you very much ma'am It was really helpful, every time I search on u tube for any geographical phenomena your channel gives easiest explaination
Very nice 👌🏼 explanation and images help to visualise the concepts, love from India 🇮🇳
i find it very hard to understand most teachers and lectures but this video has helped me understand a lot! thank u.
Glad it was helpful!

Good work, i use it for my classes as a good basic way of getting the basics right!
thanks a lot I now understand isostasy better
Amazing Explanation

oh you're awesome! I like the test!
you should include more test!
Isostasy is the equilibriumed mechanical stability between the upstanding parts and lower basins of the 🌎
Thank you 🙏🏻
Omg! Clear and elaborate!
Pause Now ❤
i love mrs.grossi
Thank you
THANK YOU
thought of asking a question but dont see replies in other comments.....
Mountain- very high
erodes
Gets higher
What's the name of the song in the silly putty scene?

Thank you :)
I'm learning Co-Art2-15
vamos a prender
Thanks v. much
samaworld please explain Hindi and bangla . think you.
cool vid yo
Why so much religeous dogma?
Isostacy is a Myth and as a result so is the Ice Age and for that matter the Ice Ages.
Thank you
