Ridge push force and slab pull are two key forces that drive tectonic plate movements. Ridge push occurs at mid-ocean ridges, where newly formed, elevated oceanic crust slides down due to gravity, while slab pull takes place at subduction zones where denser oceanic plates sink into the mantle.
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.
Three of the forces that have been proposed as the main drivers of plate movement are: • mantle convection currents – mantle currents carrying plates of lithosphere along on top, like shopping on a supermarket conveyor belt; • ridge push – newly-formed plates at oceanic ridges are warm, and so have a higher elevation at the oceanic ...
30 maj 2020 · Friction Experiments for Kids. What is Friction? Friction tries to stop objects sliding past each other. Friction allows things to start and stop moving and slows them down. Imagine sliding two strips of ribbon over each other and then think how hard it would be with two velcro strips.

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.
