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

i) Name any three fossil fuels.

ii) Which fuel is used in the production of fertilizers?

iii) What is natural gas made up of?

Answer :

i) We can list three fossil fuels as follows:

● Coal


● Petroleum


● Natural gas


Since coal, petroleum and natural gas all were formed from the dead remains (fossils) of living organisms, they all are examples of fossil fuels.


ii) Natural gas is used in the production of fertilizers. Natural gas is used as the source of hydrogen to combine with nitrogen to make ammonia (NH3) which is the foundation of a nitrogen fertilizer.


iii) Natural gas is primarily composed of methane (greater than 90%). Natural gas may also contain a small percentage of ethane, propane and higher hydrocarbons.
