2. TRIVIA
GEO - Earth
THERME - Heat

3. GEOTHERMAL ENERGY
Geothermal energy is energy formed from
heat beneath the Earth's surface. It is a
renewable source of thermal energy, though
it is not available in all parts of the world. To
use it, humans convert the thermal energy
into kinetic energy and then into electricity.
