Which statement about high pressure is true?

• A. It is associated with rising air and cloudy weather.
• B. It brings storms and heavy rain.
• C. It is associated with sinking air and clear, dry weather.
• D. It occurs only near the equator.

Answer: (C)

High pressure means sinking air in the atmosphere. As air descends, it compresses and warms, which reduces relative humidity and suppresses cloud formation. That stability leads to clear skies and dry, often calmer weather. In contrast, rising air in low-pressure systems cools and cools humidity condenses into clouds, bringing storms and heavier rain. High-pressure systems appear in various places and latitudes, not just near the equator.
