What is Geothermal Energy?

Thanks to www.eia.doe.gov for use of the above picture.	The slow decay of radioactive particles in the earth’s core, more than 4000 miles deep, is where temperatures hotter than that of the surface of the sun can be found. This process is present in all rocks at one point or another. The earth is comprised of different layers. The core of the earth has two layers, one is a solid iron and the other is made of very hot melted rock called magma. The mantle which surrounds the core is about 1,800 miles thick, and is made up of magma and rock. The crust is the outer most layer and is what makes up the earths surface. The crust can be up to 35 miles thick in some places and as thin as 5 miles in other places on the sea floor. The crust is made up of large slow moving plates which are where hot magma sometimes finds its ways through the cracks and onto the surface. Every once in a while a volcano erupts and spreads hot lava or magma over small surfaces on the earth. The presence of these hot materials under the surface is what heats the water and rock to very high temperatures. The deeper underground, the hotter these temperatures can be. People from all around the world drill wells to create electricity and to heat their homes and buildings. Another very amusing use is just to lie in a hot pool and soak in the minerals hot water for a soothing healing feeling.
