Air Masses: An air mass is a huge body of air with similar air temperature and humidity throughout.

**There are four different types of air masses that are associated with regions around the world.

The air temperature and humidity is determined by WHERE the air mass formed.

Where it formed
Continental forms over land which makes it . . .
Maritime forms over the sea which makes . . .
Tropical forms over warm areas which makes it . . .
Polar forms over cold areas which makes it . . .
Next, when you need to figure out the temperature and moisture content of the air mass. All you have to do is look at the characteristics above.
