The Earth's core will continue to have heat for billions of years. It is estimated that the core will remain hot for another 1 to 1.5 billion years before it cools down significantly.
Continents drift on top of the upper mantle. The core is much further down.
, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
Certainly, a planetary core can be cold. The heat of our own planetary core is the result of radioactive decay of various elements in the core and mantle, but eventually that heat source will be used up, and the residual heat will gradually leak away into space. There could be other planets which never had much or any abundance radioactive content in the first place.
Some of the core's heat comes from the breakdown of radioactive atoms. Much of the heat energy is left over from when Earth first formed.
The sun is millions of degrees hotter than the earths core! (:
The core is 33% of the Earths mass
No. A fusion event requires a much greater energy density than can exist at the Earth's core.

Pressure is the weight of an overlying column of material. The pressure at the core comes from 6400km of overlying rock, which is much denser than air
no the core of the earth is not solid its pretty much a liquid, since the middle of the earth is so hot, the core is like a lava substance.
Earths energy is released when there is too much heat inside of Earth and volcano's erupt.

The principle element found at the Earth's core is iron.

eventually, but it will take much longer for the engine to heat up, thus taking much longer to get heat inside of the car.
