Question

Define fossil fuel. Give suitable examples. State two precautions that should be taken in using fossil fuel to avert the energy crisis.

Answer 1

Fossil fuel:

The combustible materials formed due to the decomposition of the remains of the prehistoric animals and plants inside the Earth are called fossil fuels.

Some examples of fossil fuels are:

1. Coal
2. Natural gas
3. Petroleum

Because they are non-renewable sources of energy, we should be cautious while using fossil fuels. Two precautions that should be taken in using fossil fuels to avert the energy crisis are:

1. Fossil fuels should only be used when no alternative or renewable source of energy is available.
2. Wastage of fossil fuels should be prevented in homes, transport, and industry.
