Fossil Fuels Facts For Kids
1. What Are Fossil Fuels – Fossil Fuels Definition
- The term fossil fuel is used for the easily combustible underground deposits of organic materials that are formed from the decayed animals and plants in the geological past.
- Fossil fuels are natural fuels and include petroleum or crude oil, natural gas, and coal.
2. What Is Meant By Fossil Fuel – Fossil Fuels Meaning
- Fossil fuels mean natural fuels like coal, natural gas, and petroleum that are formed from the remains of buried organisms (animals and plants) through a natural process of anaerobic decomposition and by the exposure of excessive heat and pressure for millions of years.
3. What Is Fossil Fuel Energy – What Type Of Energy Is Fossil Fuels
- The energy of fossil fuels is chemical energy.
- Fossil fuels provide energy through a chemical reaction known as combustion.
- The energy is stored in every carbon-carbon and carbon-hydrogen bond, which is released when these bonds are break.
- When hydrocarbons (compounds of carbons and hydrogens) in the fossil fuels burn in the presence of oxygen, it produces carbon dioxide, water, and heat or energy.
- Combustion of fossil fuels is a highly exothermic (heat releasing) reaction and produces a huge amount of energy.
4. Who Discovered Fossil Fuels
- It is unknown who discovered fossil fuels.
- However, it is claimed that about 4,000 years ago, a person in northern China discovered for the first time that a black rock (coal) could burn.
- Since 1,000 BC, coal has been utilized as a fuel.
- However, coal replaced biomass as a main source of fuel during the period of the Industrial Revolution (from about 1760 to 1840).
- About 6,000 years ago, the ancient Egyptians and people living near the Euphrates river collected a black viscous liquid (crude oil) that was oozing from the ground.
- That liquid was used as a medicine for wounds and for lighting the lamps.
- At the period between 6,000 to 2,000 years ago, the ancient Persians introduced with natural gas due to the ignition of gas seeps by the lightning strikes.
5. Where Are Fossil Fuels Located
- Fossil fuels are not evenly located across the planet earth.
- The world largest deposits of coal are located in the United States, Russia, and China.
- Countries like Australia, South Africa, and India also have fairly large coal deposits.
- The largest reserves of oil and natural gas in the world are mostly located in the Middle Eastern countries and also in the Russia, Canada, Venezuela, and United States, while to a less extent in some other countries of the world.
6. Where Do Fossil Fuels Come From
- Scientists believe that fossil fuels come from the dead remains of organisms.
7. What Are Fossil Fuels Made From
- Fossil fuels are made from the dead matters of plants and animals over the course of hundred millions of years.
- Crude oil or petroleum is made up of different kinds of hydrocarbon molecules of lower to higher molecular weights.
- Natural gas has methane as a basic component along with other lower weight (short chain) hydrocarbon molecules.
- Hydrocarbons are organic compounds made up of hydrogens and carbons.
- Coal is a combination of carbon, hydrogen, oxygen, sulfur, and nitrogen and exists in a variety of forms.
8. How Do Fossil Fuels Form
- Fossil fuels were formed from the anaerobic decomposition of the ancient organisms (plants and animals).
- The period in which the fossil fuels were formed is known as the “Carboniferous period” (about 360 to 286 million years ago) that was part of the Paleozoic Era (545 to 251.9 million years ago).
- At that period, there were marshes on the land and large leafy plants and huge trees were in abundance while the seas and oceans were filled with algae.
- Upon their death, all the organisms (plants and animals) sank to the bottom of oceans and marshes.
- Their dead matter formed a spongy material known as “peat”.
- Over the course of millions of years, layers of clay, sand, and other minerals covered peat and made a rock known as the sedimentary rock, beneath which peat started to decompose.
- From the peat, different types of fossil fuels formed on the basis of the combination of organic materials, the amount of temperature and pressure, and the time of decomposition.
- Long leafy plants and huge trees converted to coal, which became hardened by the excessive pressure and heat.
- Small organisms like phytoplankton and zooplankton transformed into crude oil.
- Natural gas was also formed from the phytoplankton and zooplankton, however, it underwent more heat and pressure that caused its further decomposition and conversion into a gaseous form.
9. How Long Do Fossil Fuels Take To Form
- The formation of fossil fuels take hundreds of millions of years.
- Coal in Britain started to form about 300 million years ago.
- The oil deposits in the North Sea are nearly 150 million years old.
- The estimated time for most of the fossil fuels that started to form is around 370 million years ago.

13. How Is Energy Produced From Fossil Fuels – How Do Fossil Fuels Work
- In fossil fuels, every bond within hydrocarbon molecules stores a great amount of energy, which is released upon breaking.
- To produce power or electricity, fossil fuels are burned to heat water and produce steam.
- The steam then lay pressure on the turbine and forced the blades within it to rotate.
- The turbine is connected with a generator that has a rotor, which is a moving or rotating component.
- The rotor is attached with large electron magnets situated within a rectangular coil of copper wires.
- As the rotor within the generator spins, the spinning magnets attached to the rotor causes the electrons within the copper coil to flow.

- When natural gas burn, nitrogen oxides (NO𝒙) produces and emits into the air and play a key role in smog formation.
- The air pollution due to fossil fuels causes serious health problems in the public, particularly respiratory problems, causes premature death of the children, and increase the economic burden on society.
- The mining of coal and the drilling of oil and natural gas seriously contaminate the underground and the lake or sea waters of the surrounding areas.
- The outflow of highly acidic water from a coal mine is called the acid mine drainage or acid rock drainage that also contain heavy metals like copper, lead, and arsenic.
- Such acidic water alters the PH of the neighboring streams and lakes to the same level as a vinegar.
- The most dangerous effect of the burning of fossil fuels is its contribution to global warming.
- The burning of fossil fuels produces greenhouse gases, which trap heat and do not allow it to go back.
- Methane, the component of natural gas, emits from the transportation pipelines and from the drilling wells.
- Methane is a much more potent greenhouse gas than CO₂ and approximately 34 times more effectively trap heat on the time scale of over 100 years, while 86 times more effective over the time scale of 20 years.
- Due to global warming, the sea level is rising by the melting of glaciers and ice of the poles, which is disturbing the balance of the natural processes.
- The mining and drilling of coal and oil also cause land degradation.
16. Efficiency Of Fossil Fuels
- Efficiency is the measurement of the conservation of energy or work in a process.
- Efficiency = Output Energy ⁄ Input Energy *100%

- In the process of energy production from fossil fuels through modern electrical power generating plants, the overall efficiency is approximately 40 to 45%.
- While this value for some of the old plants is as low as 30%.
- It means that about 60% of the input energy is lost or wasted.
- Of all the fossil fuels, coal has the highest efficiency value which is approximately 45%.
17. How Are Fossil Fuels Used To Generate Electrical Energy
- To generate electrical energy, fossil fuels are used to heat water for the production of steam.
