Question

1. when air masses collide, they create fronts that bring changing weather. a. what type of front is formed when a warm air mass replaces a cool air mass? (1 point) b. how does the pressure and temperature of each air mass cause changes? (4 points) c. what weather does this type of front bring? (1 point)

Explanation:

A.

A warm front is formed when a warm air mass replaces a cool air - mass. Warm air is less dense and rises over the cooler air.

B.

The warm air mass is less dense and has lower pressure compared to the cool air mass. As the warm air rises over the cool air, it cools and condenses, leading to cloud formation and precipitation. The temperature difference causes the movement of air masses and weather changes.

C.

A warm front typically brings gentle rain or light precipitation, followed by a rise in temperature and a change to milder weather.

Answer:

A. A warm front.
B. Warm air is less dense and has lower pressure. It rises over cool air, cools, condenses, causing cloud formation and precipitation. Temperature difference drives air - mass movement and weather change.
C. Gentle rain or light precipitation, followed by a temperature rise and milder weather.
