5pts question 7 cold polar air often has high relative humidity, while desert air often has low relative humidity. this is because polar air usually contains more water vapor than desert air. o true o false

True

Explanation:

As the term Arid is used to describe the deserts i.e the air over the deserts is less moist hence the amount of water holding capacity in the air is low and as compared to that of the higher altitudes the air picks more humidity and more moisture thus this leads it to generate more of the moisture content and the more the moisture heavier the air is as compared to that of the arid regions.

this is a good question! i'll do some research and come back when i have the answer!
