What name is given to the heat energy obtained from the hot rocks inside the earth ?
Geothermal energy
Geothermal energy is the energy obtained from the earth(geo) from the hot rocks present inside the earth. It is produced due to the fission of radioactive materials in the earth’s core which results in intense heating . The areas that absorb the heat the most are called hot spots. They cause water entrapped deep inside the earth to form super heated steam. As more and steam is formed, it gets compressed at high pressure and comes out in the form of hot springs . This produces geothermal power.
