Answer:
Ozone is the layer of atmosphere found above the stratosphere. It is the layer formed by natural occurring chemical reactions.
Step-by-step explanation:
It involves ultraviolet radiation coming from the sunlight as well as molecules of oxygen that composes twenty one percent of the atmosphere.
During the reaction, the ultraviolet rays breaks down the oxygen molecule to form two oxygen atoms and then these two oxygen atoms which are highly reactive combines with another oxygen atom to form ozone molecule (
).
