Answer
Highly energetic ultraviolet radiations from the sun breaks the oxygen molecule [O2] into two oxygen atoms. This chemical reaction is called photodissociation or photolysis.
The highly reactive oxygen atom [O] can then react with oxygen molecule [O2] to form ozone [O3]
O2 [O] + [O]
O2 + [O] ⟶ O3 [ozone]
