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
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. For 10 points, identify these regions at which an oceanic plate slides under another tectonic plate.
