Why is the desert dry?
Why is the desert dry?
Air at the equator rises and cools – condensation then forms rain. The air then moves north and south until it gets to about 30° north and south of the equator, where it sinks. This air is dry and no condensation can form, so there is no rain.
Why is the desert so hot?
Deserts are hot primarily because of a lack of water. When the sun shines on the ground, all of the absorbed sunlight goes into raising the ground’s temperature. DESERTS ARE COLD AT NIGHT:Because of the lack of water in the ground, and little water vapor in the air, most deserts can get quite cool at night.
