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 … WebHow the Ozone Layer Forms and Protects When UV light hits oxygen gas, it breaks it down to two oxygen atoms. Then, when an oxygen atom meets oxygen gas, it forms ozone gas. NASA Most ecosystems rely on the …
