An energy resource which uses heat from underground rocks is known as geothermal energy. This is considered to be the best form of green energy.
Geothermal energy is the name associated with this energy source. Iceland relies heavily upon geothermal for heating because of its extensive number of underground and surface heat sources.
Geothermal energy
it sends out thremal heat
The energy resource would be the heat in the rocks in this case. Note 1: I am not aware of any technological project that tries to do just that - extract heat from rocks. However, it should be possible in principle. Note 2: This is only possible if the rocks have a higher temperature than the surroundings. For more information, you may want to read about heat engines, and about the Carnot cycle.
When heat is removed from the hot rocks underground (by cycling water down to them) the rocks renew their heat from the nearby lava and magma. It is very rare that this doesn't happen quickly.

Geothermal energy
good it is a renewable energy resource found in rocks underground (heat from the rdioactive rocks)
it sends out thremal heat
Geothermal energy uses the heat of underground rocks to generate electricity. This is a renewable resource, because the rocks continue to be heated by uranium deposits in situ.

Coal is a rock-like fossil fuel produced from dead plants and animals over millions of years.

Geothermal energy uses heat from underground.
well, a type of energy is kinetic, sound or gravitational potential energy, whereas an energy RESOURCE is where energy is from, like heat from a flame, the heat is the type of energy and the flame is the resource. hope this helped! answered by Sarah x

Underground geo means earth and thermal means heat so from the heat underground
