Question

How does ozone layer is made

Answer 1

Ozone is produced naturally in the stratosphere when highly energetic solar radiation strikes molecules of oxygen, O₂, and cause the two oxygen atoms to split apart in a process called photolysis. If a freed atom collides with another O₂, it joins up, forming ozone O₃.

O₂+hν → 2[O]

O₂+[O]  ⇄ O₃
