Air masses are huge expanses of air that form from differential heating in the atmosphere. The boundary between two air masses is called a weather front. Fronts can create particular types of weather. Identify each front by the weather it produces.

Question

warm
stationary
cold
occluded
A:A cold air mass advances on a warm air mass, causing rain.

B:A warm air mass advances on a cold air mass, causing rain.

C:Air masses that are close in temperature collide, typically leading to mild weather.

D:Three air masses meet, usually leading to strong winds and heavy rain.
