Answer the following questions:
The small ozone layer on top of the stratosphere is crucial for human survival. Why?
The small ozone layer on the top of the stratosphere absorbs ultraviolet radiations, γ-rays, cosmic radiations etc., from the sun. So, these radiations, which can cause genetic damage to the living cells, are prevented from reaching the earth. Thus, the small ozone layer on top of the stratosphere is crucial for human survival.
