Th process that powers plate tectonics is what?

The process that powers plate tectonics is primarily driven by mantle convection. Heat from the Earth's interior causes the semi-fluid mantle to move, creating convection currents that push and pull the tectonic plates on the Earth's surface. Additionally, slab pull and ridge push forces contribute to the movement of these plates. This dynamic system leads to geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.
