What is the original source of all of the energy on Earth?

Answer 1

God

Answer 2

Geologists used to believe that there was a hot accretion of the earth. Now a cold accretion is generally more accepted. With the cold accretion, hydrocarbons, particularly methane was present in the upper couple of hundred miles of crust and mantle. These hydrocarbons upwelled due to their volatile nature and low density. These encountered a deep biosphere that produced more complex hydrocarbons, encountered reducing environments (low oxygen states) where coal formed, or encountered water at high pressure and formed methane hydrate deposits in the ocean. This accounts for the so called fossil fuels. Radioactive isotopes decaying is responsible for some of the earth's interior heat as well as the original heat when it formed. It takes a long time to cool since it is many thousands of miles thick so it retains it heat very well.

Answer 3

First, God. Without him, there is no life possible on earth. Second, the sun provides about 99% of the energy for all the living organisms on earth. Rest 1% accounts for the gravitation of the moon that causes tides in the ocean. The energy within the earth, known as geothermal energy, also account for some of the energy ultilized by living organisms.

Answer 4

Most is from the sun, but you also have the heat that is generated in the earth's core. ocean waves carry some energy too.

Answer 5

The sun and then green plants and from those two things we got everything relating to energy.

Answer 6

the big bang
without it you would not have the heavier elements needed to form earth or the sun.

Answer 7

The sun. That is unless you go all the way back to the BIG BANG.

Answer 8

Hydrogen atoms.

Answer 9

The Big Bang ...
