Final answer:
The main sources of energy that drive Earth's geologic change are heat energy from the sun and the Earth's interior, and gravitational energy from the moon and the sun.
Step-by-step explanation:
The two main sources of energy that drive most of Earth's geologic change are heat energy from the sun and from the interior of the Earth, and gravitational energy imparted by the moon and the sun. Geothermal energy originates from heat rising to the surface from the Earth's molten iron core and from heat produced by radioactive decay in the Earth's crust.
Tidal energy arises from the gravitational attraction of the moon and the sun on the Earth's oceans combined with the Earth's rotation.
