Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
