How does a dead animal or plant become a fossil fuel?

Answer 1

the dead plants and animals compile on top of each other, most oil or deposits of coal are roughly 300 million years old or more. the carbon in these deposits stay while the rest of or most of the organic matter kind of drifts off if you will. anthracite, the purest form of coal is 91.5% carbon or more by standards. the deposits, like i was saying stack on top of each other over this time period and start drying out and cementing together. same in the cases of oil. but the mass amounts of these "fossil" fuels we find were once all marshlands and swamps that is why the organic matter stayed in place so long and became what is destroying our beloved planet today. but basically we are burning the suns energy because if u want to trace it back far enough, the animals ate plants and the plants ate nothing, they got energy through the sun from photosynthesis and that is what stayed so long the carbon and organic matter that they became.

Answer 2

When a dead animal or plant is buried under layers of sediment, it is subjected to high pressure and heat over millions of years. This process breaks down the organic matter, transforming it into fossil fuels like oil, coal, and natural gas. These fuels retain energy from the original living organisms and can be extracted for human use.

Answer 3

Their deceased bodies got covered in earth over time. The pressure and heat compressed the carbon in their bodies to become fossil fuels.

Answer 4

Eventually, yes. But it takes a million years or so.

Answer 5

it decomposed

Answer 6

Plants.
