Question

Quizplus · Accepted Answer

The process described in the question is that of subduction, which involves the submergence of one tectonic plate beneath another. This is a common process in areas where two plates converge, such as along the Pacific Rim where the Pacific Plate is subducted beneath other plates. Rifting refers to the process of two plates moving apart from each other, compression involves the squeezing of rock layers leading to deformation, and isostatic uplift refers to the rise of land due to changes in the Earth's crust caused by erosion or tectonic activity.
