Question

explain how ozone in the stratosphere is formed.

Explanation:

Ozone in the stratosphere forms when oxygen - molecules (O₂) are split by ultraviolet (UV) radiation into individual oxygen atoms. These oxygen atoms then combine with other oxygen - molecules to form ozone (O₃). The chemical reactions are: O₂ + UV → 2O; O + O₂ → O₃.

Answer:

Ozone in the stratosphere is formed when UV radiation splits oxygen - molecules into oxygen atoms, which then combine with oxygen - molecules to create ozone.
