Ok, so how do you solve the problem posed by this image?BennyTheJett wrote:Density times thickness equals density times thickness. That's why different topographies can be equal in weight. The image is more detailed. you take the density times thickness of the crust, and it equals the density times thickness of this other crust. If they are equal there is equilibrium.

Re: Dynamic Planet B/C
All the yellow (crust) must have an equal density times thickness for there to be isostatic equilibrium. If the numbers aren't equal the smaller number is sinking (I think).WangwithaTang wrote:Ok, so how do you solve the problem posed by this image?BennyTheJett wrote:Density times thickness equals density times thickness.

Re: Dynamic Planet B/C
You do realize that most of the math on the test is about glacial movement, erosion, and mass balance right. THere's not much you can do with isostasy when it comes to glaciers.WangwithaTang wrote:Ok, so how do you solve the problem posed by this image?BennyTheJett wrote:Density times thickness equals density times thickness.

Re: Dynamic Planet B/C
This is false, the melting and formation of large glaciers cause the Earth's lithosphere to rebound and move down, respectively.Sharan.thiru wrote:THere's not much you can do with isostasy when it comes to glaciers.

Re: Dynamic Planet B/C
Thank you! Can somebody explain the difference between hanging valleys, truncated spurs, and U-shaped Valleys are? Sorry for all the question guys I'm new to dynamic planet.BennyTheJett wrote:All the yellow (crust) must have an equal density times thickness for there to be isostatic equilibrium.

Have you looked at pictures? I find that visuals really help me with all the glacial features.WangwithaTang wrote:Thank you!

That’s weird since I’ve never seen isostasy problems at any competitor ion.

Re: Dynamic Planet B/C
It may help to consider that Division B and Division C tests likely focus on different aspects of the event.Sharan.thiru wrote:That’s weird since I’ve never seen isostasy problems at any competitor ion.
