In what form is the stored energy in fossil fuels?

Answer 1

Fossil fuels rely on the Sun's energy because the energy in fossil fuels came from plants and algae as they performed photosynthesis, which requires sunlight. This energy was stored in the form of sugars, and when the plants and algae died, they were eventually buried and heated to a point where they were turned into a fossil fuel, which contained the solar energy the plants had stored in their lifetimes.

A:Fossil Fuels originate from the transformation of residual organic matter within sedimentary rocks, a process that takes million years to occur.

Organic residues issued from dead organisms (plants, plantkon, etc) are mostly mineralized into CO2 in the water column (sea borders, lakes) and at the surface of sediments. However, under certain conditions (anoxicity), organic materials are preserved and trapped within sediments. As a result of sediments burial, organic matter is submitted to higher pressure and temperature and becomes thermally unstable. It then transforms into water, CO2 and hydrocarbons.

Fossil fuels exist because life exists at the Earth's surface. Photosynthesis is the process by which CO2 is transformed into organic matter that constitute living organisms. The energy for phtosynthesis comes from the sun, so indeed one can say that sun is the origin of fossil fuels.

Answer 2

Fossil Fuels are made from dead animals and plants from up to 300 million years ago. Fossil Fuels are non-renewable

Answer 3

Chemical energy, which was originally obtained from the sun by long dead lifeforms.

Answer 4

Because of the chemicals in the fossil fuels

Answer 5

Fossil fuels are energy sources derived from the remains of decomposed ancient plant and animal bodies. What helps create the energy is the process of photosynthesis.

Answer 6

A molecule of a fossil fuel is merely just a long hydrocarbon chain like methane (CH4), however, fossil fuels are rarely just hydrocarbons.

Answer 7

chemical bonds

Answer 8

Chemical Energy.
