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.
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.
