In atmosphere, some OXYGEN (O2) absorbed energy from ultraviolet (UV) ray and split to for single oxygen atoms. This oxygen combined with remaining oxygen and form ozone (O3) molecule.
Stratospheric ozone. Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere. ... In the second step, each of these highly reactive atoms combines with an oxygen molecule to produce an ozone molecule (O3).
