According to the passage, why does Antarctica have low moisture levels?

• A. Cold air holds more moisture.
• B. Cold temperatures result in less precipitation.
• C. Geographical features block rain.
• D. Local flora absorbs moisture rapidly.

Answer: (B)

Antarctica has low moisture levels primarily due to the influence of cold temperatures on precipitation. In cold climates, the atmospheric conditions are not conducive to holding moisture in the air, which leads to reduced precipitation. Essentially, cold air is less capable of retaining water vapor compared to warmer air, which means less moisture is available to fall as snow or rain. This is a critical factor in Antarctica's climate, contributing to its status as a polar desert with extremely low humidity and precipitation rates. While there may be opinions related to geographical features or flora, these aspects do not play as significant a role in explaining Antarctica's moisture levels compared to the direct impact of cold temperatures on precipitation.
