Radioactive decay of natural elements (Uranium is a big one) releases a large amount of energy, this energy heats up the earth. These elements are in the crust (underground) the mantly and the core. So the warmth they produce keeps the earth warm. Without this, the core would have cooled down and solidified by now.

Naturally occurring radioactive decay deep inside the Earth creates geothermal energy.
idk :D
Geothermal heat energy from inside the earth is caused by the radioactive decay of Uranium in the mantle.
The inside of the Earth, if you go down past the crust, is quite hot, but it does not contain fire. The heat of the Earth's interior results from the radioactive decay of elements deep inside the Earth, rather than from combustion. There is no air inside the Earth, and nothing could burn there.
It is warmed by geothermal energy which is created by RADIOACTIVE DECAY http://en.wikipedia.org/wiki/Geothermal_(geology)
That's because of where each of these processes occur. There is no nuclear fusion inside of Earth. There is probably a small amount of radioactive decay in the Sun, but the power produced by it is insignificant, compared to the huge amount of power produced by nuclear fusion.
The Earth's core contains many radioactive elements within its core that emit warmth as they decay, keeping the core of the Earth hot and heating it from within. Meanwhile, the sun is a product of the nuclear fusion of hydrogen into helium and its rays warm the Earth's crust from outside.
The answer here would be Radioactive Decay.

Source of heat in mantle come from radioactive decay of the radioactive elements inside the earth..

From the inside of the Earth, which is fairly hot. The Earth gets its heat from radioactive decay.

"geothermal" (the source is a combination of original impact energy and radioactive decay.)
