Wegener's original name for the supercontinent was
when two tectonic plates converge and one slips under the other, a zone is formed.
the movement of a tectonic plate away from a mid-ocean ridge can be measured by the orientation of the field.
the process of heating the mantle from the core of the earth causes expansion and movement of material in a cell, which is partly responsible for the movement of continents.
gravity is also 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.
