Answer:
Explanation:
Ozone is naturally produced in the stratosphere
by a two- step reactive process. In the first step, solar ultraviolet radiation (sunlight) breaks apart an oxygen molecule to form two separate oxygen atoms.
In the over- all process, three oxygen molecules plus sunlight react to form two ozone molecules.
