I believe It's the earths mantle. But I'm not 100% positive!

The deepest scientist have been able to study earths interior depth is 12,262 meters
The forces that receive energy from Earth's interior include volcanic activity, plate tectonics, and geothermal energy. These processes are driven by the heat generated within the Earth's mantle and core, which result in movements of the Earth's crust and the release of energy in various forms.
Seismic waves
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
The earths interior is cold
A body wave is a seismic wave that travels through Earths interior.
