Question : what is the difference between fossil fuels and mineral fuels?
Im doing an assesmnet in science about energy and one of the goals is the difference between fossil fules and mineral fuels, if you know this please answer it.Thanks in advance.

All Answers: Answer #1Fossil fuels or mineral fuels are fossil source fuels, that is, hydrocarbons found within the toplayer of the earth’s crust.They range from veryvolatile materials with low carbon:hydrogen ratioslike methane, to liquid petroleum to nonvolatilematerials composed of almost pure carbon, likeanthracite coal. Methane can be found inhydrocarbon fields, alone, associated with oil, orin the form of methane clathrates. It is generallyaccepted that they formed from the fossilizedremains of dead plants and animals[1] by exposureto heat and pressure in the Earth's crust overhundreds of millions of years.[2] This is known asthe biogenic theory and was first introduced byMikhail Lomonosov in 1757. There is an opposingtheory that the more volatile hydrocarbons,especially natural gas, are formed by abiogenicprocesses, that is no living material was involvedin their formation.It was estimated by the EnergyInformation Administration that in 2005, 86% ofprimary energy production in the world came fromburning fossil fuels, with the remainingnon-fossil sources being hydroelectric 6.3%,nuclear 6.0%, and other (geothermal, solar, wind,and wood and waste) 0.9 percent[3]Fossil fuels arenon-renewable resources because they take millionsof years to form, and reserves are being depletedmuch faster than new ones are being formed.Concern about fossil fuel supplies is one of thecauses of regional and global conflicts. Theproduction and use of fossil fuels raiseenvironmental concerns. A global movement towardthe generation of renewable energy is thereforeunder way to help meet increased energy needs.Theburning of fossil fuels produces around 21.3billion tonnes (= 21.3 gigatons) of carbon dioxideper year, but it is estimated that naturalprocesses can only absorb about half of thatamount, so there is a net increase of 10.65billion tonnes of atmospheric carbon dioxide peryear (one tonne of atmospheric carbon isequivalent to 44/12 or 3.7 tonnes of carbondioxide).[4] Carbon dioxide is one of thegreenhouse gases that enhances radiative forcingand contributes to global warming, causing theaverage surface temperature of the Earth to risein response, which climate scientistsagree[attribution needed] will cause major adverseeffects, including reduced biodiversity and, overtime, cause sea level rise.
