The temperature of a desert is also a defining and unique characteristic. Most deserts are warmer during the day than they are at night, and the difference in temperature is quite drastic. The average daytime temperature is 100Â°F, while at night the average temperature is 25Â°F. This large temperature difference is due to low amount of moisture in the desert air.
By the way, approximately 1 in. (2.5 cm) of rain falls in dry deserts per year. The average annual temperature of these miles of hot sand is 64Â° F (18Â° C). The latitude range is 15-28Â° north and south of the equator. Their global range covers about 1/5 of the earth, including the world's great deserts: Sahara, Sonora, Thar, Kalahari and the Great Australian. Plants of the Dry Desert have adapted to the lack of water by using dew for moisture and taking in water through their leaves and stems.
