Definition of ozone for English Language Learners. : 1  a form of oxygen that is found in a layer high in the earth's atmosphere. : 2  fresh healthy air especially near the sea.
Ozone is formed naturally in Earth's upper atmosphere. When the oxygen gas (O2) in the atmosphere is exposed to ultraviolet light, the chemical bond between the two oxygen atoms is broken. The extra oxygen atom bonds with an existing O2 molecule in the atmosphere, forming ozone (O3). Ozone is also formed from car exhaust, which contains nitric oxide (2NO), an unstable nitrogen and oxygen molecule.
