An air mass that forms over Texas will be a ____?Question 1 options:


continental polar air mass


continental tropical air mass


maritime polar air mass


maritime tropical air mass

Answers

Answer: continental tropical air mass

Explanation:

The continental tropical mass of air forms over the Texas. It forms in the interior of the subtropical continents at about 150 to 350 North to South latitude. They can be characterized by the dry and hot air masses due to the temperature and moisture present in their source region. The tropical air masses originate in the tropical regions (warm regions) these typically have low air pressure.

Answer:

2

Explanation:

continental tropical air mass
