Answer:
Ozone layer
Explanation:
The ozone layer found in the stratosphere is responsible for protecting the earth against harmful radiation.
In the lower atmosphere, the ozone is a pollutant and very harmful to life.
- Ozone is an oxygen molecule made up of 3 atoms of oxygen covalently bonded to one another.
- It usually found in the ozone layer within the stratosphere just above the reaches of the troposphere.
- Ozone cuts off and absorb harmful ultraviolet rays emanating from the sun.

Air is a mixture of many gases of which ozone is not a part of.
