Plate Tectonics: Plate boundary with subduction

Click on the surface of Earth where there is a convergent plate boundary with subduction.

Consider this schematic cross section illustrating typical depths and elevations of different features on Earth. The shape and elevation of the features can give you enough information to interpret the tectonic environment in which it formed.
