Image. A large drawing labeled Schematic Cross Section of Plate Tectonics. The drawing labels various geological formations and activities in the ocean: convergent plate boundary, transform plate boundary, divergent plate boundary. Emerging forms under the ocean include strato-volcano, island arc, shield volcano, and trenches. On land are a volcanic arc (a mountain range) and continental rift zone (also in a mountain range). Under the earth’s crust are subducting plate, mantle, hotspot, lithosphere, asthenosphere, oceanic crust, and continental crust. Source U S Geological Survey.
