<P> Ridge push or sliding plate force is a proposed driving force for plate motion in plate tectonics that occurs at mid-ocean ridges as the result of the rigid lithosphere sliding down the hot , raised asthenosphere below mid-ocean ridges . Although it is called ridge push , the term is somewhat misleading ; it is actually a body force that acts throughout an ocean plate , not just at the ridge , as a result of gravitational pull . The name comes from earlier models of plate tectonics in which ridge push was primarily ascribed to upwelling magma at mid-ocean ridges pushing or wedging the plates apart . </P>
