Explanation:
Geothermal energy is the source of energy that comes from the heat within the earth. "Geothermal" is derived from the Greek words 'geo' which means earth and the word 'therme' means heat. Geothermal energy is used to produce electricity, to heat the buildings and greenhouses, and for other purposes.
Geothermal energy is stored and can obtained from deep inside the earth. Inside the earth surface, there are various layers of earth crust called the crust, mantle and the inner core. As we go deep inside the earth, it becomes more and more hot, the temperature increases. So one has to drill deep inside the earth crust ti find the super heated fluids and extract the heat in the form of geothermal energy.
