Question

Quizplus · Accepted Answer

Deep-sea trenches are formed by the convergence of two tectonic plates, where one plate sinks beneath the other in a process called subduction. This subduction creates volcanic activity, which lead to the formation of volcanic arcs along the edge of the overriding plate. Therefore, all deep-sea trenches border volcanic arcs.
