Question

Fossil fuels are formed by decomposition of biomass buried under the earth over millions of years ago. Name any two fossil fuels.

Answer 1

Hint:Fossil fuels are the fuels which are found in the earth surface. Fossils fuels formed due to the decompositions of living organisms for millions of years under the surface. Most of the fossil fuels are the main source of energy to human civilization.

Complete answer:
For many years, fossil fuels have been generating almost all of the energy that is required to run our cars, keep our businesses, and light the lights on in our homes. Name of the two main fossil fuels are:
-Natural Gas
-Petroleum

Natural gas is a gas form of hydrocarbon that is non-toxic, smells less, and colourless. It contains methane as its main content. They are mostly found near other fossil fuel sources like coal and petroleum. However, in many cases, gas reservoirs also seem to exist without any oil. It is also known as dry gas.

Natural Gas in its purest form cannot be used. Instead of that, it is processed into more cleaner fuel for consumption for the masses. When processing the gas, also many other gases are produced as by-products. That includes nitrogen, propane, ethane, carbon dioxide, which can be utilized for other purposes.

Among all of the other fossil fuels, natural gas is the purest form of them. Contrast to coal, it releases approximate half of the carbon dioxide and only one-tenth of pollutants when that is used for electricity production. Importantly, the effect of fossil fuels like natural gas on our environment is less.

Petroleum or crude oil is another type of fossil fuel that is seen to be found buried deep under the earth's surface. The word Petroleum was deduced from the two Latin words 'Petra' that means rock and 'oleum' means oil. Most of the Petroleum found on the surface of the earth till date is formed during the Mesozoic period when plankton, algae, and other living organisms got buried deep under the seafloor.

Note: At present days, oil, coal, and gas provide us about 90 percent of our energy needs. Coal, crude oil, and natural gas all are regarded as fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago. They were decomposed by microorganisms that started the formation of fossil fuels.Fossil fuels have a high carbon content.
