How do CFCs deplete ozone layer?

Explanation

### Step-by-Step Solution:

1. **Understanding CFCs**: Chlorofluorocarbons (CFCs) are chemical compounds made up of carbon, chlorine, and fluorine. They were commonly used in refrigeration, air conditioning, and aerosol propellants.

2. **Release into the Atmosphere**: When CFCs are released into the atmosphere, they eventually rise up to the stratosphere, where the ozone layer is located.

3. **Interaction with Ultraviolet (UV) Rays**: The ultraviolet rays from the sun interact with CFC molecules. This interaction provides enough energy to break the bonds in CFCs.
