When two tectonic plates converge and one slips under the other, a/an zone is formed.
The process of heating the mantle from the core of the earth causes expansion and movement of material in a/an cell, which is partly responsible for the movement of continents.
Gravity is responsible for the movement of continents in two ways: through at subduction zones as gravity drags a plate downward, and through as gravity pushes plates downslope, away from the center.
When two opposing plates meet and scrape against one another at a fault, stress is created when the two moving plates catch or stick together. As this stress is released, a/an occurs.
The Ring of Fire is a region of intense volcanic and seismic activity that borders the Plate.
