The formation of fossil fuels is the result of a natural processes like anaerobic decomposition of dead organisms. Age of organisms and fossil fuels is a result of million years and sometimes more than 600 million years. Fossil fuels have high concentration of carbons that includes petroleum, coal and natural gas but often question arise “How Are Fossil Fuels Made”.

Fossil fuels are available in various forms. Since past, the most useful source of fuel in man's life is fulfilled with the use of fossil fuel. Fossil fuel is organic prehistoric remaining of plant as well as animals. They are major source of electric power of the world and meet the demand of total energy requirement. Fossils are non- renewable form of energy source that was formed during carboniferous era. Fossil fuels are made up of animal mater and plants. At the time of decomposition of body after the death of plant or animal buried under many layers, fossil fuels are formed.

Natural gas and oil are formed in the same manner but coal has quite different story of its creation. Natural gas and oil is formed by the decomposition of aquatic plants under river. After many years, combination of bacteria under pressure formed ONG. After formation, it started rising up on the surface from ground level but hard rock obstruct it in doing so. Because of which, it was hard for Oil to come on the surface. However, Caprock prevent them from splitting in down water level. Coal is quite different due to its formation that is not similar to that of Oil and Natural Gas.

In modern era, fossil fuel acts as an important source in generating energy. However, entire world argue on the benefits of fossil fuels and its impact on the earth's environment. Number of websites provides you details regarding the structure and uses of fossil fuels. For classes of 6th to 8th standard of CBSE board, you can download videos, solutions, and test material from these websites. The most important reason behind the fame of fossils is that they have high-energy value. Fossil fuels are secure in nature as compared to other fuels regardless of the fact that they are extremely combustible material.

Increase in the percentage of Sulfur Dioxide in the air is because of fossil fuels that release it. After reacting with moisture present in the air, Sulfur Dioxide forms Sulfuric Acid and results in acid rain. Severe damages are caused by acid rain and human beings are the main sufferer. If you want to refer history of fossil fuels, you can access websites containing topics like “How Are Fossil Fuels Made”, “Advantages and Disadvantages of Fossil Fuels” and many more.
