Ridge push (also known as gravitational slides 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.
Ridge-Push Force. Let's cover a final force a subducting plate would experience, the ridge-push force. This force results from the elevation of oceanic ridges above the seafloor. This difference in height leads to pressure that 'pushes' the plate away from the ridge.
Definition. Plate Driving Forces: The forces that drive the motions of tectonic plates at the surface. Slab Pull: The force exerted by the weight of the subducted slab on the plate it is attached to. Ridge Push: The pressure exerted by the excess height of the mid-ocean ridge.

One side in the argument holds that the plates are only moved by the traction caused by mantle convection. The other side holds that traction plays only a minor role and that two other forces, ridge push and slab pull, are more important. Some argue that the real answer lies somewhere in between.
1 sty 2021 · These sublithospheric buoyancy forces generate the plate-driving forces Fsp (slab pull) and Frp (ridge push).
Ridge push force influences tectonic plate movement by causing newly formed oceanic crust at mid-ocean ridges to slide away due to its elevated position. As magma erupts at these ridges and cools, it creates new crust that is warmer and less dense than the older crust.
