Question

Explain why trees are renewable resources and coal is not a renewable resource?

Answer 1

Answer:

Coal is a non-renewable source of energy because it has accumulated in the earth over a very very long time, and if all the coal gets exhausted, it cannot be produced quickly in nature. Wood is considered a renewable source of energy because if trees ate cut to obtain wood, then more trees will grow in due course of time.

Answer 2

Many trees can be planted and then used for our needs. Re-afforestation can ensure that we continue to get benefits of trees and not degrade the environment. Hence, they are renewable.

Coal is a fossil fuel that takes million of years to form. Before more coal forms, we can exhaust all the coal that exists and accessible. Thus it's non-renewable.
