Geothermal energy is the energy drawn from the earth (geo) by way of the hot rocks that are found there. It is created as a result of the tremendous heating caused by the fission of radioactive elements in the earth's core.
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move can reveal a lot to scientists about the composition of the Earth.
It is thought that the Earth's core temperature ranges between 5,000 to 7,000 degrees Celsius. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.
