How is thermal energy within the earths layers of related to some of its natural disasters

Heat flow and movement of material within the Earth causes geological features and disasters to form because all this movement is responsible for the motion of tectonic plates.

Explanation: Movement within the Earth causes tectonic plates to move (tectonic plates are pieces of Earth's crust and upper mantle; also referred as the lithosphere). In addition, this movement is what causes the many geological features and disasters written above. Moreover, the way that this works is that convection currents in the mantle (inside the Earth) causes tectonic plates to move when material near the Earth's core rises, and colder mantle rock sinks. In addition, this movement allows for the creation of many geological features.
