Question

study the image of an air mass.
which major type of air mass is moving into the area?
cold air mass
○ maritime polar
○ continental polar
○ maritime tropical
○ continental tropical

Explanation:

1. Recall air mass types: Maritime (forms over water), Continental (forms over land); Polar (cold), Tropical (warm).
2. The image shows a "Cold air mass" over the interior (land) of North America.
3. Continental Polar (cP) air masses form over cold, continental regions (like northern Canada/central US in winter) and are cold, dry. Maritime Polar would form over oceans, Maritime Tropical over warm oceans, Continental Tropical over warm land (dry, hot). So the cold, continental origin matches continental polar.

Answer:

B. continental polar
