How is geothermal energy created?

The Earth basically has several layers in its core. The very center is the inner core, and it has an outer core that is surrounded by magma. Magma is the hot melted rock that erupts from volcanoes. A mantle surrounds both the inner and outer core. Finally, the crust is the outermost layer of the Earth that has water and land on it. The Earth’s crust is surrounded by plates, and when certain mantle rocks melt they become magma. This magma starts to rise to the Earth’s crust, generating heat from below. When the magma reaches the surface it becomes lava, like out of a volcano. But when it stays below the surface it remains trapped. How does geothermal energy create electricity? Geothermal power is created by turbine generators that use the steam, heat and hot water from geothermal reservoirs to create electricity. The water that is not used is then returned back to the reservoir and kept heated. What is geothermal power used for? Thousands of years ago geothermal energy was use for ...  more
