What power source uses the earths internal heat
nlexa [21]

Answer:

Geothermal power comes from Earth's internal heat

Explanation:

The description applied to power sources tends to match the names applied to the source of energy. Sometimes Latin, or other word derivations are used.

For example, "hydro-" refers to water, so it is no surprise that hydroelectric power comes from the movement of water. Of course, "nuclear" refers to the nuclei of the atoms that are split to release energy in a nuclear power plant. Similarly, "geo-" refers to Earth, and "thermal" refers to heat, so "geothermal" energy is the name given to energy derived from Earth's heat.
