A
low dew point
B
high pressure system
C
high dew point
D
low pressure system
AI Explanation
The correct answer is D) low pressure system. A barometer showing falling pressure indicates the approach of a low pressure system. Low pressure systems are typically associated with unsettled, stormy weather as air rises and cools, often producing clouds, precipitation, and strong winds. In contrast, high pressure systems are linked to stable, fair weather as air sinks and warms. The dew point, which is the temperature at which water vapor in the air condenses, is not directly related to barometric pressure changes.
