What happens to the weather during the passage of a cold front?

1. Weather Clears Immediately

2. Weather Often Deteriorates

3. Temperature Rises Gradually

4. Humidity Remains Unchanged

The correct answer is: Weather Often Deteriorates

When a cold front passes through an area, it typically leads to a rapid change in weather conditions. A cold front is characterized by colder air mass moving in to replace the warmer air that was present. As the colder, denser air pushes underneath the warmer air, it forces the warm air to rise suddenly. This rising warm air can lead to the development of clouds and precipitation, often resulting in thunderstorms or heavy rain. The turbulence and lifting of air associated with this process can cause weather to deteriorate, with the potential for severe weather conditions. After the front has passed, however, the weather usually stabilizes, leading to clearer skies and cooler temperatures. In contrast, the other options do not accurately reflect the typical impacts of a cold front. Weather does not clear immediately; instead, there is often a period of intensity before stabilizing. Temperature generally drops after a cold front passes, rather than rising gradually. Additionally, humidity levels do not remain unchanged; they usually decrease after the passage of the front as the new, colder air has a lower moisture capacity compared to the warm air being displaced.
