Ozone at the higher level of the atmosphere is a product of ______ acting on oxygen molecules.
UV radiation
Correct Answer: Option 4 – UV Radiation
Explanation:
Ozone (O₃) in the stratosphere is formed when ultraviolet (UV) radiation acts on oxygen (O₂) molecules.
How Ozone is Formed:
Splitting of Oxygen Molecules
High-energy UV rays break oxygen molecules into free oxygen atoms:
O₂ → O + O (in the presence of UV radiation)
Formation of Ozone
The free oxygen atoms combine with oxygen molecules to form ozone:
O + O₂ → O₃
Thus, UV radiation is responsible for the formation of ozone in the upper atmosphere.
