* Ozone formation: Ozone (O3) is formed in the stratosphere when ultraviolet (UV) radiation from the sun splits oxygen molecules (O2) into individual oxygen atoms. These oxygen atoms then react with other oxygen molecules to form ozone.
* The reaction: The key reaction is: O2 + UV radiation → 2O, followed by O + O2 → O3.
* Dependence on oxygen: As you can see, the formation of ozone directly depends on the presence of oxygen molecules. If the concentration of oxygen decreases, there are fewer oxygen molecules available to react and form ozone. This results in a lower concentration of ozone.
In summary: Ozone formation is directly linked to oxygen levels. A decrease in oxygen leads to a decrease in ozone.
