The video explains air masses, large bodies of air with uniform temperature and humidity. It describes different types of air masses, such as maritime and continental, and their characteristics based on their formation regions. The video also covers how air masses move due to global winds, jet streams, and the Coriolis effect, affecting weather patterns.

Which region is described as having cold and dry air in the winter?

• Florida

• Arizona

• California

• Alaska

What must happen for an air mass to form?

• The air must be very humid.

• The air must stay over the area long enough to pick up its characteristics.

• The air must move quickly over the area.

• The air must be very dry.
