Answer 1

Answer:

Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth's surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity.

Geothermal energy is the heat energy from hot rock present inside the earth.

This heat comes from the fission of radioactive materials which are naturally present in these rocks.

The places where very hot rocks occur at some depth below the surface of earth are called hot spots, and are sources of geothermal energy.
