Give the names of two energy sources that you would consider to be exhaustible. Give reasons for your choices.
Answer
Two energy sources that are considered exhaustible are
- Coal
- Petroleum
Coal and petroleum are fossil fuels.
They are made by decomposition of plants and animals under high temperature of pressure, over a million of years.
The rate at which coal and petroleum are used is much higher than the rate at which they are produced, hence they can finish at any time.
Hence, they are termed as exhaustible fuels.
