E) cold, dry air moving toward the poles descends.
<u>Explanation:</u>
A large portion of the world's deserts are situated almost 30 degrees north scope and 30 degrees south scope, where the warmed tropical air starts to drop.
Hot deserts are essentially found around the Tropics of Cancer and Capricorn. As air moves inland, it gets drained of dampness and precipitation drops. So the majority of the world's deserts are situated at scopes where cool, dry air advancing toward the shafts slides.
