Question

which type of air mass forms over deserts and brings hot, dry weather?
1 maritime tropical
2 maritime polar
3 continental tropical
4 continental polar

Explanation:

Air masses are classified based on their source regions. "Continental" indicates formation over land (deserts are land - based), and "tropical" implies warm/hot temperatures. So, a continental tropical air mass forms over deserts (continental) and is hot (tropical). Maritime air masses form over water (so they are more humid, which is not the case here as we want dry weather). Polar air masses are cooler.

Answer:

1. Continental tropical
