Which statement is NOT a weather consequence of low-pressure systems?

• A. Low pressure areas produce cloudy, unsettled weather.
• B. In a low-pressure system, precipitation is common.
• C. High-pressure systems bring clear, calm conditions.
• D. High-pressure systems bring improving weather.

Answer: (D)

Low-pressure systems lift air, which cools and condenses as it rises, leading to clouds and often precipitation. That rising motion creates unsettled weather, so cloudy skies and rain or snow are typical results in a low-pressure system. The statements about high-pressure systems bringing clear, calm conditions and improving weather describe conditions that arise from high pressure, not from low pressure. Therefore, the statement about high-pressure systems bringing improving weather is not a weather consequence of low-pressure systems.
