Question

From where did the fuel come in side the earth

Answer 1

Answer:

One of the most widespread beliefs about fossil fuels — oil, natural gas and coal — is that these substances started out as dinosaurs. There’s even an oil company, Sinclair, that uses an Apatosaurus as its icon. That dino-source story is, however, a myth. What is true: These fuels got their start long, long ago — at a time when those “terrible lizards” still walked the Earth.

Fossil fuels store energy in the bonds between the atoms that make up their molecules. Burning the fuels breaks apart those bonds. This releases the energy that originally came from the sun.

Answer 2

The fuel came inside the earth from the dead remains of the plants and animals.

Coal was formed by the decay of plant ramains.

Petroleum was formed by the dead remains of plants and animals deep inside the oceans and seas.
