Question

Indications that a cold front has passed through your location could include the following: falling air temperature, falling dewpoint, ______ air pressure, and a wind shift from south to the west.

a) Rising
b) Stable
c) Increasing
d) Decreasing

Answer 1

The missing word indicating a change after a cold front has passed is 'rising,' as cold fronts typically result in rising air pressure due to the influx of denser, colder air.

Step-by-step explanation:

The indications that a cold front has passed through your location could include the following: falling air temperature, falling dewpoint, rising air pressure, and a wind shift from south to west. The correct answer is a) Rising.

When a cold front moves through an area, the denser and colder air pushes out the warmer air ahead of it, typically causing temperatures to drop. The dewpoint, which is the temperature at which air is saturated and dew can form, also falls as the cold front brings in drier air. As the cold air displaces the warm air, atmospheric pressure usually increases because cold air is more dense than warm air, exerting greater pressure on the surface. Additionally, the wind's shift from south to west is characteristic of the passage of a cold front, indicating a change in weather patterns, often associated with the clearing of clouds and reduced precipitation after the front's passage.
