Question

The ozone layer forms naturally by

• A. the interaction of CFC with oxygen
• B. the interaction of UV radiations with oxygen
• C. the interaction of IR radiations with oxygen
• D. the interaction of water vapour and oxygen

Hint:

UV radiation plays a crucial role in the formation of ozone in the stratosphere.

Answer 1

The Correct Option is B

The ozone layer forms when ultraviolet (UV) radiation from the Sun interacts with oxygen molecules (O$_2$), splitting them into individual oxygen atoms (O).
These atoms then react with other O$_2$ molecules to form ozone (O$_3$).
