Answer: Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Explanation:
The amount of carbon in the form of carbon dioxide in the atmosphere is about 0.03% by volume. This value is kept fairly constant by a natural process known as the CARBON CYCLE. This involves carbon dioxide being continually removed from the atmosphere by plants in photosynthesis, rain water as weak acids while in order to maintain this balance, carbon dioxide is at the same time returned to the atmosphere by:
--> burning of carbon containing substances (fossil fuel)
--> respiration of plants and animals and
--> Decomposition of organic substances.
Therefore the role of fossil fuels which are rich in carbon content releases carbon into the atmosphere when burnt.
