What drives the platentectonics?

Plate tectonics is driven primarily by the heat from the Earth's interior, which causes convection currents in the mantle. These currents create movement in the lithosphere, the rigid outer layer of the Earth. Additionally, gravitational forces and the Earth's rotation play roles in influencing plate movements, while subduction zones and mid-ocean ridges contribute to the recycling and creation of tectonic plates. Overall, the combined effects of heat flow, gravity, and mantle dynamics drive the movement of tectonic plates.
