In the stratosphere, ozone is created primarily by ultraviolet radiation. when, high energy ultraviolet rays strike ordinary oxygen molecules $(\mathrm{O}_{2})$, they split the molecule into two single oxygen atoms, known as atomic oxygen. A free oxygen atom then combines with another oxygen molecule to form a molecule of ozone. There is so much oxygen in our atmosphere, that these high energy ultraviolet rays are completely absorbed in the stratosphere, $\mathrm{O}_{2} + h v \xrightarrow[\text{ discharge }]{\text{ Electric }} 2 \mathrm{O}$ $\mathrm{O} + \mathrm{O}_{2} \longrightarrow \mathrm{O}_{3}$
