Question

Statement 1: CFC's cause the depletion of the ozone layer.

Statement 2: CFC's disturb the ozone-oxygen cyclic process.

• A. Statement 1 is true and statement 2 is false
• B. Statement 2 is true and statement 1 is false
• C. Statement 1 and statement 2 is false
• D. Statement 1 and statement 2 is true

Answer 1

The correct option is D

Statement 1 and statement 2 is true

Chlorofluorocarbons are responsible for the depletion of the ozone layer.

The CFC's released reach the stratosphere and break down in the presence of UV rays to release chlorine. This chlorine converts the ozone molecules to oxygen molecules. This disturbs the cyclic process of the ozone-oxygen cycle which maintains a constant ozone amount.
