Do oxygen exist above the ozone layer ?  
Asked by pawanky31 | 28 Jun, 2018, 10:44: AM
answered-by-expert Expert Answer

Ozone is a form of oxygen. Oxygen occurs in three different forms in the atmosphere; as oxygen atoms (O), as oxygen molecules (O2) and as ozone (O3). Ozone in the Earth's stratosphere is created by ultraviolet light striking ordinary oxygen molecules containing two oxygen atoms (O2), splitting them into individual oxygen atoms (atomic oxygen). The atomic oxygen then combines with unbroken O2 to create ozone, O3. Hence, it is not possible to obtain oxygen in the molecular form above the ozone layer since ozone itself is obtained from oxygen.
