Ozone hole is most clear over

Options

A. Artic region
B. Pacific region
C. Antartic region
D. Gulf region

Answer

**Step-by-Step Solution:**

1. **Understanding the Ozone Layer**: The ozone layer is located in the stratosphere, which is the upper part of the atmosphere. It plays a crucial role in protecting life on Earth by absorbing harmful ultraviolet (UV) radiation from the sun.

2. **Identifying Ozone Depletion**: Ozone depletion occurs when substances like chlorofluorocarbons (CFCs) break down ozone molecules in the stratosphere. This leads to a thinning of the ozone layer.

3. **Recognizing the Regions Affected**: Ozone depletion is observed in various regions, but it is most pronounced in specific areas due to climatic and atmospheric conditions.

4. **Determining the Region with the Most Clear Ozone Hole**: Among the regions mentioned (Arctic, Pacific, Antarctic, and Gulf), the Antarctic region is known for having the most significant and clear ozone hole. This phenomenon is primarily due to the unique weather patterns and colder temperatures that facilitate the breakdown of ozone.

5. **Conclusion**: Therefore, the ozone hole is most clearly observed over the Antarctic region.

**Final Answer**: The ozone hole is most clear over the Antarctic region.
