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 is a geological process that occurs at mid-ocean ridges, where the elevation of the ridge causes tectonic plates to move away from each other. This force is generated as hot magma rises to create new oceanic crust, leading to a slope that encourages the movement of plates downward and outward.
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.
3 paź 2024 · As the crust moves away from a mid-ocean ridge, it cools and becomes denser and thicker. This causes the lithosphere to slope away from the ridge and gravity pulls the lithosphere down this slope, pushing it forwards. This is known as gravitational sliding (or ridge push)
Ridge push occurs due to gravitational forces acting on elevated mid-ocean ridges that push plates apart, while slab pull happens when a denser, subducting plate sinks into the mantle, pulling the rest of the plate along with it.
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.
Ridge-push forces cause two plates to pull apart on the surface. Slab-pull forces pull the plates down. This movement of out and down is also encouraged by convection traction, or clockwise and counterclockwise currents that are present beneath the plates.
