The heat at the centre of the earth is thought to be caused by the decay of radioactive materials, such as uranium, thorium and possibly an isotope of potassium. However this is currently not confirmed.
protons
No the heat would be to much pressure
galileo came across that the earth was not the center
The sun provides heat to the Earth.
convection currents
Lava is created/stored at the center of the earth. The center of the earth is very warm because the earth absorbs some( i believe 5%) of the heat give off by the sun.
The center of the earth is hot because of heat retained from when the planet formed, frictional heating and heat that comes from the decay of radioactive elements.
As we get closer to the center of the earth, the gravity of earth increases and the heat too increases...thats what i think.
No, you can not get to the center of the earth. The core of the earth, which is the center of the earth, is way to hot. It would be like standing on the sun, but though the core of the earth is EXTREMELY hot, it can not compare to the heat of the sun
Radioactive Decay
moon
Wind
the center of the Earth
from steam produced by earth
moon
rotation of the earth's core
it comes from the center of thy earth
