how does the inside of the earth remain hot?

Answer 1

Some would say the mere pressure of the earth keeps the core molten and hot

Answer 2

It's boiling with molten hot. Much like the fusion process the reaction in neutrons and protons basically keep it fired up like a nuclear reactor. The reason this happens is because the world exploded and was sucked back together quickly by the magnetic field surrounding it. All particles in the reactor stage are formed and tightened down in the center of the earth much like a nuclear reactor it contours to bleed and absorb, but but when she bleeds that force must go somewhere and so the volcano erupts releasing the pressure.

Answer 3

Outer solid layer does not allow heat to dissipate heat to get the inside liquid layer of earth to cool. Are you physics student? Why you are seeing inside? Should you look at titles while questioning and answering?

Answer 4

Gravity, immense pressures, and crust insulation.

Oh, the earth is actually cooling down very very slowly as it's also slowing in its rotation.

Answer 5

How does coffee in a thermos stay hot? How does your house stay warm in the winter? How do you stay warm when outside in cold weather..........

All the same thing.

Answer 6

It started that way and has never cooled

Answer 7

pressure

Answer 8

some thing to do with nature.

Answer 9

Good question..

Answer 10

insulation
