Question

Which of the following will be released during combustion of fossil fuels ?
A.Carbon dioxide
B.Oxide of nitrogen
C.Carbon monoxide
D.All of the above

Answer 1

Hint: We know the burning of fossil fuels is one of the main reasons for the greenhouse effect , this is because when fossil fuels are burned greenhouse gases are released and they are called so because they absorb heat .

Complete step by step answer:
Fossil fuels such as coal , oil and natural gas are created when organic matter decays and is compressed beneath layer upon layer of sand , earth , rock and ocean .
As fossil fuels are composed mainly of hydrocarbons , when combustion of fossil fuels takes place , carbon dioxide is released mainly from burning of coal .
They also release oxides of nitrogen on combustion which is responsible for the formation of smog and acid rain . Also carbon monoxide is released when car engines burn fossil fuels .
Apart from these many other gases such as sulphur dioxide , mercury compounds and other greenhouse gases are also released in the environment .
Hence , option D is correct since all of the given three gases are released during combustion of fossil fuels .
All these gases are responsible for polluting the environment and increasing the greenhouse effect .
Hence option D is correct .


Note:
The use of fossil fuels should be done carefully as they are non - renewable resources , that is their supply is limited . Also they release greenhouse gases because of which global warming is increasing .
