Wait, so what's the equation? Like for the image. Because d*t = d*t are like the same thing

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. If unequal, there is depression or rebound.

Ok, so how do you solve the problem posed by this image?

This is false, the melting and formation of large glaciers cause the Earth's lithosphere to rebound and move down, respectively.

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.

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).

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.

Yep, I've seen isostasy questions at almost every competition I've gone to.

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