Where did the energy of fossil fuel came from?

Answer 1

Fossil energy comes from the sun. All fossil fuels are ancient remains of living plants and animals. Plants use solar energy to make compounds with high energy content from simpler compounds, like CO2 and H2. Animals get all of their energy from plants, ultimately, so if either plants or animals die, energy from the sun will be stored in the dead matter. After millions of years of being buried, sediment will pile on top of this dead matter and refine it into coal, natural gas, or oil, depending on various factors. Those energy sources are very high in energy from the sun.

Answer 2

• Crude oil is formed from the remains of prehistoric plankton and algae that settled to the bottom of a body of water in an oxygen deprived environment. Coal was formed from plant matter on the surface of the earth that was buried under mud and sediment. Over geologic time these organic materials were buried under more and more mud creating intense heat and pressure which caused the organic matter to undergo chemical changes, eventually resulting in what we know as fossil fuels.
• We get it from organic (once alive) matter in sedimentary rocks

Fossil fuels come from deep within Earth's crust. These fossil fuels are the product of many years of pressure and dampness.

Answer 3

Yes gasoline is a byproduct of diesel refinement which is made from crude oil which is just hydrocarbons made up of plants and animals compressed over millions of years, although 10% (depending on the state) is ethanol made from corn.

Answer 4

generally through mining
