Question 717Navigation General

70% to pass

A katabatic wind blows _______________.

A in a circular pattern
B up an incline due to surface heating
C horizontally between a high and a low pressure area
D down an incline due to cooling of the air
AI Explanation

The correct answer is D) down an incline due to cooling of the air. A katabatic wind is a type of downslope wind that blows down an incline due to the cooling and subsequent increasing density of the air. As the air cools, it becomes denser and flows downslope under the influence of gravity. This is in contrast to anabatic winds, which blow upslope due to surface heating. The other options are incorrect because: A) katabatic winds do not blow in a circular pattern, C) they are not horizontally-flowing winds between high and low pressure areas.
