Ozone `(O_(3))` depletion is due to

Options

A. PAN
B. `NO_(2)`
C. CFCs
D. Sulphates

Answer

### Step-by-Step Solution:

1. **Understanding Ozone Formation**:
- Ozone (O₃) is formed in the atmosphere when ultraviolet (UV) rays from the sun split diatomic oxygen (O₂) molecules into individual oxygen atoms (O).
- These free oxygen atoms can then react with other O₂ molecules to form ozone (O₃).

2. **Location of Ozone**:
- Ozone is primarily located in the stratosphere, which is a layer of the Earth's atmosphere.
- Its main function is to absorb and protect the Earth from harmful UV radiation.

3. **Causes of Ozone Depletion**:
- Various human-made chemicals are responsible for the depletion of ozone.
- These chemicals, when released into the atmosphere, can reach the stratosphere and lead to the destruction of ozone molecules.

4. **Identifying the Pollutants**:
- The primary pollutants responsible for ozone depletion are chlorofluorocarbons (CFCs).
- Other substances that contribute to ozone depletion include carbon tetrachloride and methyl chloroform.

5. **Conclusion**:
- Therefore, the depletion of ozone (O₃) is primarily due to the release of CFCs and similar compounds into the atmosphere.

### Final Answer:
Ozone (O₃) depletion is due to chlorofluorocarbons (CFCs) and other related pollutants.
