Continental air masses form in the United States
Maritime polar, maritime tropical, continental polar, & continental tropical
the continental tropical is made up of the warm, dry air from Mexico
Under oceans its five km and on continental masses its thirty five to sixty five km
Glaciers can form U shaped valleys.
This is ultimately the result of temperature differences; the energy comes from sunlight. Note that air masses need to travel in BOTH directions, since the air can't just accumulate in one place.

The 4 major air masses are continental polar (cP), continental tropical (cT), marine polar (mP) and marine tropical (mT). Generally, continental air masses are drier than marine air masses, and polar air masses are cooler than tropical air masses. cT air masses are relatively limited in distribution existing in the south west North America and North Africa.
The five types of air masses are polar, tropical, maritime, continental, and arctic. Polar air masses are cold and dry, tropical air masses are warm and dry, maritime air masses are warm and moist, continental air masses are dry and cold, and arctic air masses are extremely cold and dry.
Continental polar air masses originate over cold, dry regions in the northern hemisphere, such as northern Canada and Siberia. These air masses form when cold air masses move southward from the polar regions and become isolated over land, leading to cooling and drying.
The US is not a great place for air masses to form because it is surrounded by oceans on three sides, which limits the development of continental air masses. In addition, the complex topography and variability of the climate in the US make it difficult for stable air masses to form and persist over large areas.
Continental polar air masses form over cold, dry land areas near the poles, such as Siberia in Asia and northern Canada in North America. These air masses are responsible for bringing cold temperatures and dry weather when they move southward.
