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 contributes to plate movement by creating a gravitational force that encourages tectonic plates to slide away from mid-ocean ridges. As new oceanic crust forms and elevates the ridge, it creates a slope that aids in this movement.

Ridge push is a geological process that occurs at mid-ocean ridges, where the elevated position of the ridge causes the surrounding tectonic plates to be pushed away from the ridge and towards subduction zones.
Ridge push is a geological process that occurs at mid-ocean ridges, where the elevation of the ridge causes a gravitational force that pushes tectonic plates away from the ridge. This phenomenon is significant in the movement of plates within the Earth's lithosphere, playing a key role in plate tectonics and geodynamics.

There are three main forces that determine the rate at which tectonic plates move as part of the mantle convection system: slab pull: the force due to the weight of the cold, dense sinking tectonic plate. ridge push: the force due to the buoyancy of the hot mantle rising to the surface beneath the ridge.
