Question

Explain why coal, petrol and diesel oil will be exhausted one day.

Answer 1

because they are non renewable resources.

Answer 2

coal petroleum and diesel oil are made of carbon compounds which are found in large number in carbohydrates which is a major source of good for all living beings and that's the reason the bodies of humans and plants contain carbon. So when plants and animal die their bodies take time to decompose ultimately forming carbon . But the death rate of plants and animals is less than growth rate. So dead bodies will be same but growth will be more so carbon content will be reduced and thus coal petroleum and diesel will come to an end.
