Energy that is stored in earth is called a Geothermal energy. Geothermal energy is extracted from the head obtained in earth’s core. This is one of clean sources of energy because it releases little greenhouse gases. Geothermal energy is natural source of energy.
Heat is continuously produced by earth since Geothermal energy is a renewable energy source
Geothermal energy is a renewable energy source because the heat is continuously produced inside the Earth. Geothermal energy is found near area where volcanic activity has occurred, the head provide from volcanic activity can provide geothermal energy
Hot rock, hot liquid, or in steam form are where Geothermal energy can be found.
