Fossil Fuels :: Coal Petroleum Natural Gas

Part One - IntroductionFossil Fuels be the closely important zipper sources in our world today. The overwhelming majority of the energy used in the world comes from the burning of three major fogy fuels coal, petroleum, and natural gas. Fossil fuels are a non-renewable source of energy. They are form over a very long period of time the dodo fuels on earth today were formed from plants and animals that lived up to 300 million years ago. These fossil fuels are found in deposits deep downstairs the earth. The fuels are burned to release the chemical energy that is stored within this resource. heartiness is essential to modern society as we know it. over 85% of our energy demands are met by the combustion of fossil fuels.Part ii FormationGoing back to the earlier days of Earth, the plants and animals that lived then in conclusion died and decomposed. The majority of these life forms were ocean dwelling forms of plankton. When these ancient ocean dwellers died, they roll up on the bottom of a seabed this is how a good muckle of our fossil fuel reserves began. The actual transformation process of these prehistorical creatures is not known, but scientists do know that the atmospheric pressure, heat, and a great masses of time go into the making of fossil fuels. Geologists are fairly definite that the beds of organic remains mixed with silt and mud to form layers. Over time, mineral sedimentation formed on top of the organisms, effectively entombing them in rock. As this occurred, pressure and temperature increased, these conditions, and possibly other unknown factors, caused organic textile to break down into the simpler form of hydrocarbons, which are chains of carbon and total heat ranging from simple configuration to complex compounds. Another affect of extreme pressure is that the vegetable oil and gas which are various mixtures of hydrocarbons raise upwards to the surface. incisively when in the conversion process and the nature of this migra tion is not known and is thing to conjecture. Oil and gas are found in the ground, not freely drifting up through the earth. This is because the hydrocarbons come across rock formations that they are unable to penetrate. Complex rock structures that effectively trap gas and oil are formed by tectonic plate activity, the same forces that firing continents. The most common formation that accomplishes this is called an anticline, a dome or arching layer of rock that is impermeable by oil and gas.
