Question

Quizplus · Accepted Answer

The crustal, gravitational balance idea, also known as isostasy, suggests that the Earth's crust is in gravitational balance. When a mountain range undergoes erosion, the removal of material reduces the mass on that part of the crust, leading to a slow uplift as the crust adjusts to regain equilibrium. This is because the crust behaves somewhat like a floating object that rises when weight is removed, maintaining gravitational balance.
