Ozone hole is maximum over

Options

A. India
B. Pakistan
C. Australia
D. Antarctica

Answer

**Step-by-Step Solution:**

1. **Understanding the Ozone Layer**: The ozone layer is a protective layer in the Earth's stratosphere that absorbs most of the Sun's harmful ultraviolet (UV) radiation. It is primarily composed of ozone (O3) molecules.

2. **Impact of Pollution**: The ozone layer is being depleted by pollutants, particularly chlorofluorocarbons (CFCs). These substances break down ozone molecules, leading to the formation of an "ozone hole."

3. **Geographical Focus**: The question asks where the ozone hole is maximum. Research indicates that the depletion of the ozone layer is most severe over specific regions.

4. **Identifying the Location**: The maximum depletion of the ozone layer, or the largest ozone hole, occurs over Antarctica. This phenomenon is primarily due to the extreme cold temperatures in the stratosphere during the Antarctic winter, which facilitates the breakdown of ozone.

5. **Conclusion**: Therefore, the ozone hole is maximum over Antarctica.

**Final Answer**: The ozone hole is maximum over Antarctica.
