Subduction zones are broad areas where two. plates are moving in opposite directions. The. oceanic plate descends beneath a continental. plate in this example. [See Divergent and. Convergent Plate Boundaries for more-. detailed depictions].
Subduction zones are sites of high rates of volcanism, earthquakes, and mountain building. Orogenesis, or mountain-building, occurs when large pieces of material on the subducting plate (such as island arcs) are pressed into the over-riding plate or when subhorizontal contraction occurs in the over-riding plate.
