Months in which ozone hole appears over poles is

Options

A. June-July
B. August-September
C. October-November
D. December-January

Answer

To determine the months in which the ozone hole appears over the poles, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Ozone Hole**: The term "ozone hole" refers to a significant thinning of the ozone layer, particularly over polar regions. It is not a literal hole but rather a region where the concentration of ozone is greatly reduced.

2. **Identifying the Polar Regions**: The ozone hole is primarily observed over the Antarctic region, which is located at the South Pole. This phenomenon is less pronounced in the Arctic region, but it can occur there as well.

3. **Seasonal Patterns**: The ozone depletion process is influenced by seasonal changes. In the polar regions, particularly Antarctica, the conditions for ozone depletion are most favorable during the spring months.

4. **Specific Months**: Research indicates that the ozone hole typically forms in the Southern Hemisphere's spring, which occurs from August to September. The maximum depletion is usually observed in September.

5. **Conclusion**: Based on the above analysis, the months in which the ozone hole appears over the poles, particularly Antarctica, are August to September.

### Final Answer:
The ozone hole appears over the poles primarily in **August to September**.
