Where does the heat at the center of the Earth come from?

Answer 1

"The planet's internal heat was originally generated during its accretion, due to gravitational binding energy, and since then additional heat has continued to be generated by the radioactive decay of elements such as uranium, thorium, and potassium. The heat flow from the interior to the surface is only 1/20,000 as great as the energy received from the Sun."

Answer 2

My short solutions are not unsolicited mail. they could be sarcastic, inspite of the undeniable fact that. about 6 ft down, the mandatory temp. is about 57 stages 3 hundred and sixty 5 days round. that's adequate to apply a warmth pump to convey warmth up right into a house in the wintry climate - or to take up warmth, and cool a house in the summer season. it is executed each and each of the time. As to a satellite tv for pc close to the solar - how are you going to get the ability from the satellite tv for pc to the earth? that's some distance for an extension wire.

Answer 3

Two sources -- radioactive decay of elements like uranium and thorium (which, because of their density, are more prevalent in the Earth's core), and heat resulting from gravitational contraction as the Earth formed.

Answer 4

It must be the friction of space? Chemical reations in the material of the earth. It could not be Nulear reaction since that only occurs in stars and inthe sun.
The flow of Induced electric current due to the flow of water on the surface of the earth(water is like a magnet when it moves)
It could not be a coulling process because by now the earth would be as cold as the moon.

The Best way to scientifically answer this dellema is to make a scientific experiment and measure the effects of the motion of the oceans.On the magnetic fields of the earth and their interactions.

Answer 5

Earth's unusual internal heat is caused by radioactive decay of unstable nuclei. Each time a nucleus decays, it not only emits a decay particle, it also emits energy (E = mc2).

Answer 6

The mass was originally molten. It floated layers according to density and solidified from the outside in.

Answer 7

Friction, not pressure. Friction of the molten material that's down there. Eventually, with no motion down below, the Earth would cool off and become very, very cold, even though there's a lot of pressure in the middle.

Answer 8

Comes from nuclear reactions in the Earth´s core, if I remember correctly.

Answer 9

Friction AND pressure AND radiactive decay.

Answer 10

Pressure. Think how much rock, both solid and molten, is pushing down on that layer of material.
