Question:

Give the names of two energy sources that you would consider to be exhaustible. Give reasons for your choices.

Answer:

Two exhaustible energy sources are as follows: coal and wood

 

(a) Coal: It is formed from the remains of dead plants and animals that have been buried under the earth’s crust for millions of years. It takes millions of years to produce coal. Industrialization has increased the demand of coal. However, coal cannot replenish within a short period of time. it is a nonrenewable or exhaustible source of energy.

(b) Wood: It is obtained from forests. Deforestation at a faster rate has caused a reduction in the number of forests on our planet. It takes hundreds of years to grow a forest. If deforestation is continued at this rate, then there would be no wood left on the Earth. Hence, wood is an exhaustible source of energy.
