In this article, we will discuss the Fossil Fuels Definition, Examples, Compotition, and Benefits
Fossil Fuels Definition
Fossil fuels commonly referred to as mineral fuels are fuels derived from weathering the remaining living things that make up petroleum, coal, natural gas. The production and use of fossil fuels causes environmental problems. Like, we often know a lot of water and air pollution in general.
Fossil fuels are a common term for flammable geological deposits buried from organic matter, formed from decaying plants and animals that have been converted into crude oil, coal, natural gas, or heavy oil with exposure to heat and pressure in the Earth’s crust over hundreds or millions of years.
Excessive burning of fossil fuels such as greenhouse gases, i.e. Excess carbon dioxide, can lead to global warming. And also a small amount of hydrocarbon fuel is a bio fuel obtained from carbon dioxide in the atmosphere so as not to add carbon dioxide in the air. The global movement towards renewable energy generation is undertaken to help meet increasing energy needs.

Examples of fossil fuels
Here are some examples of fossil fuels, including:
Oil
Fossil fuels derived from petroleum are natural oils found underground, this fossil fuels are very important. This is because it is not widely used in the original state, but it is processed into fuels such as gasoline, kerosene, paraffin and others.
Oil is one of the most commonly used fossil fuels. Because the oil and its products are very beneficial for life today.
Heavier crude oil, especially those extracted from tar sands and through fracking from shale, requires the use of energy-intensive methods that produce more emissions and environmental degradation compared to conventional oil. As conventional oil from underground reservoirs runs out, more oil producers turn to unconventional sources such as tar sands and shale oil.
Natural gas
Another widely used fossil fuel is natural gas. Natural gas can usually be found underground alongside petroleum and coal. This fuel produces relatively little pollution when compared to other fuels.
Coal
This one fossil fuel is formed from vegetative deposition that occurs for thousands of years. Fossilized forms of decaying plants and other vegetation have formed coal. In the United States, coal is used to generate more than 50 percent of electricity. Coal-fired power plants require large reserves of coal to generate electricity constantly.
Fossil fuels composition
Petroleum is a liquid hydrocarbon derived from the remains of plants and animals in the oceans.
Petroleum is formed as a result of:
- Decay of the remains of living beings by microorganisms.
- The remains of living things are buried in the layers of the earth’s crust.
- Increased temperature and pressure turn the rest of living things into petroleum.
- Petroleum gets into the pores of the soil and it is concentrated in an impermeable area.
Petroleum comes from the oceans, and it is on land due to the movement of the earth’s plates
Coal is a solid hydrocarbon derived from the remains of plants that form burnable sedimentary rocks.
Natural gas is a hydrocarbon gas derived from the remains of plants and animals in the oceans, and formed in conjunction with petroleum.
| Fossil fuels | Composition |
|---|---|
| Crude oil | – Alkanes (n-heptane, n-octane and isooktana) – Cycloalkanes (cyclopentane and cyclohexane) – Benzene – Few alkenes, S, N and O |
| Coal | – High tribe hydrocarbons – Little S |
| Natural gas | – Alkanes (methane, ethane, propane, and butane) – CO2, H2S, He |
Benefits of Using Fossil Fuels
In the last half of the 18th century, windmills and water energized to grind flour, sawn wood, or pump while wood or peat was used to provide heating in winter.
The widespread use of fossil fuels was initiated by coal and then petroleum, to power steam engines enabling an industrial revolution. At the same time, the light of gas using natural gas or coal gas becomes widespread.
The discovery of internal combustion engines and their use in cars and trucks increases the need for gasoline and diesel, both made from fossil fuels.
Other means of transportation, railways and planes, also require fossil fuels.
Other fossil fuel uses include power generation and the biochemical industry. Asphalt, the remnant of petroleum extraction, it is used to build roads.
