Question

Quizplus · Accepted Answer

Deep ocean trenches develop where oceanic lithosphere (the outermost layer of the earth's crust) meets a plate carrying continental or oceanic crust and bends downward, forming a subduction zone. The sinking lithosphere melts and forms magma that rises to the surface, creating volcanic arcs or island chains.
