Question 2(c)

Give a geographical reason for each of the following:

(i) Petroleum is called 'liquid gold'.

(ii) Natural gas is a fossil fuel.

(iii) CNG is an eco-friendly fuel.

Answer

(i) Petroleum is called 'liquid gold' because there is not even a tiniest part of crude petroleum which goes to waste or remains unused.

(ii) Natural gas is a fossil fuel because it has been formed by decomposing remains of dead animals and plants buried under the earth.

(iii) CNG is an eco-friendly fuel because it causes less damage to the environment as it is made up of methane and results in less carbon emissions.
