Geothermal energy means energy stored as heat in the earth. You know that below the earth's crust lies a layer called the mantle.
The temperature near the upper part of the mantle is around 1500 C. The material here is in a partially molten state and is called magma. In some areas, hot magma swells up into the crust, but remains trapped below the surface of the earth. Such areas in the earth's crust are called hot spots, The rocks and groundwater above these hot spots get heated. At some places, the hot water comes to the surface and collects in pools called hot springs. In some cases, the water gets converted to steam. Steam or steam mixed with hot water pushes out of the surface of the earth with great force. The fountain of steam and water coming out from the surface of the earth is called a geyser.
