What type of weather change is commonly associated with the passage of a cold front?

• A. Gradual decrease in humidity
• B. Steady temperature increase
• C. Sudden drop in temperature and possible storms
• D. Unchanging weather conditions

Answer: (C)

The passage of a cold front is typically characterized by a sudden drop in temperature and the potential for severe weather, including thunderstorms or storms. As the cold front advances, it pushes warm, moist air upwards rapidly. This upward movement can lead to the development of clouds and precipitation, often resulting in a dramatic and sudden change in weather conditions.

When a cold front moves through an area, the leading edge of the cold air mass replaces the warm air that has been present. This rapid displacement is what causes the temperature to drop sharply as cooler air floods in. Additionally, the lifting of warm air can lead to intense storm development, which is why thunderstorms are often associated with cold fronts.

Other options do not accurately reflect the typical weather changes associated with cold fronts. For example, a gradual decrease in humidity would usually be seen with dry air masses, while a steady temperature increase is more characteristic of warm fronts moving in, where warmer air replaces cooler air gradually. Unchanging weather conditions do not align with the dynamic nature of cold fronts, which are known for causing significant shifts in weather patterns.
