what is fossil fuels?

Answer 1

Fossil fuels are so called because it's "fossilized" biomass from earlier epochs in earth's history. So, examples would be oil, shale oil, tar sands, coal, natural gas deposits, etc. Almost any hydrocarbons found in geological structures. Some controversal theories have been proposed to explain a non-biological origin of some of the oil, but not proven.

Answer 2

Fossil fuels are decomposed biomass that has been heated compressed and turned into hydrocarbons. There are three main forms of fossil fuels; 1) Coal, 2) Petroluem, 3) Natural Gas.
Now there are many other forms but they can be fitted into these 3 categories like gasoline and coke are forms of Petroluem. Anyway theses fossil fuels are used as our main energy source as 90% of our electricity is produced by Coal fired plants in north america.

Fossil fuels do not wreck the ozone as one person pointed out. What wrecks the ozone is CFC's. Fossil fuels produce greenhouse gases which trap thermal radiation in our atmosphere. Ozone reflect UV rays from coming in. Bit of a difference.

HOpe that helps

Answer 3

Oil, natural gas, coal... anything we use for fuel today that is carbon based and biologic in origin - they formed from ancient plants and animals, hence fossils. These are naturally occurring material within the Earth's crust. When burned with air (or oxygen), they produce energy.

Answer 4

Oil and coal. Eons ago when the dinosauars died off, ancent forests, long gone now were crushed and heated by the globe-they were turned into "fossil fuel" that we today want so badly so we can drive half a block to get a soda, that we will go to war for it.

Answer 5

Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.[1] The theory that hydrocarbons were formed from these remains was first introduced by Mikhail Lomonosov in 1757. In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources. These are sometimes known instead as mineral fuels. The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years. [2]

When generating electricity, energy from the combustion of fossil fuels is often used to power a turbine. Older generators often used steam generated by the burning of the fuel to turn the turbine, but in newer power plants the gases produced by burning of the fuel turn a gas turbine directly.

With global modernization in the 20th and 21st centuries, the thirst for energy from fossil fuels, especially gasoline derived from oil, is one of the causes of major regional and global conflicts. A global movement toward the generation of renewable energy is therefore underway to help meet the increased global energy needs.

The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming. The atmospheric concentration of CO2, a greenhouse gas, is increasing, raising concerns that solar heat will be trapped and the average surface temperature of the Earth will rise in response. A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.

Answer 6

that's what Fred Flintstone used in his car for fuel.

Answer 7

Those r hydocarbons, natural gas and coal left behind by decaying animals and plants millions of years ago. they r used to make petrol, diseal, kerosine, spirit, butane,charcoal etc.

Answer 8

coal

stupid fuels that ruin the ozone layer
