Question

Quizplus · Accepted Answer

Isostatic adjustment refers to the balance between the weight of the Earth's crust and the buoyancy of the mantle beneath it. As mountains and ice sheets form and grow, they exert more weight on the crust, causing it to sink deeper into the mantle. As they erode or melt away, the crust rebounds upward due to the buoyancy of the mantle. This process is most closely associated with buoyancy, as stated in choice D.
