For 10 points, identify these regions at which an oceanic plate slides under another tectonic plate.
Seismic activity in these regions originates in a deep location known as a Wadati-Benioff zone, and volcanoes that occur above them often form in arcs. These areas are frequently the sites of orogeny and lead to a dominant source of mantle convection via the sinking of the lithosphere. The process which occurs at these convergent boundaries is contrasted with the process of an oceanic plate moving over a continental plate, obduction.
