Geothermal energy comes
September 4th, 2010Geothermal energy comes from reserves of water located in the Earth’s layer of magma. Magma, otherwise known as molten rock, is a super hot substance that springs directly from the Earth’s core, which is a scalding 9,000 degrees Fahrenheit. Magma heats the reserves of water located in its midst to very high temperatures, around 700 degrees Fahrenheit. These geothermal reservoirs, as they are known, can be drilled into or can escape naturally through cracks in the Earth’s crust. These natural formations create such places on Earth as hot springs and geysers.
Geothermal energy can be traced back to 10,000 years ago when Native Americans used geothermal water found in hot springs to cook and for use as medicine.
