Notes
- An air mass is a large volume of air with the same temperature and moisture content.
- it takes on characteristics of the area over which it develops
- Air masses extend over large bodies of land or water and form in about a week
- Air masses can be classified based on the area of origination and moisture.
- Continental air mass is really cold and dry; Continental Polar air masses are very cold, dry; Maritime Polar air masses are cool and moist; Maritime Polar air masses are cool and moist; Maritime Tropical air masses are warm and moist; Continental Tropical air masses are hot and dry.
- Continental polar: Very cold and dry; Maritime tropical: Warm and moist; Arctic: Very cold and dry
- All of them are right.

|
WarmA warm front occurs when slower moving warm air replaces replaces retreating cooler air.
Weather: warm temperature, light to moderate rain, and higher humidity. |
StationaryThis front occurs when neither front is moving.
Weather: rain for long periods of time. |
