How did the ozone form

WebOxygen (O 2) production on Earth started over two billion years ago by the splitting of water molecules by the sun and more significantly, through the photosynthesis of blue-green algae in the oceans.Over millions of years, O 2 began to accumulate in Earth’s atmosphere. Ozone also began to form through photochemical dissociation in which O 2 molecules … WebOzone is Earth's natural sunscreen, shielding life from excessive amounts of ultraviolet radiation. But Earth's ozone layer has been damaged by well-intentioned chemicals—chlorofluorocarbons, used for refrigerants and aerosol spray-cans—that have the unintended consequence of destroying ozone molecules.
