Although ridge-push/slab-pull is the favoured mechanism for plate motion, it’s important not to underestimate the role of mantle convection. Without convection, there would be no ridges to push from because upward convection brings hot buoyant rock to surface.
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 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.
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.
