What is the processes that cause motion within Earth?

Motion within Earth is primarily caused by processes such as mantle convection, which involves the movement of semi-molten rock in the mantle due to differences in temperature and density. Additionally, plate tectonics play a major role in Earth's motion, as the movement of tectonic plates at the surface leads to phenomena like earthquakes and volcanic eruptions. The rotation of Earth on its axis also contributes to various motions, such as ocean currents and the Coriolis effect.
