Detailed explanation-1: -The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night. The daytime temperature averages 38°C while in some deserts it can get down to-4°C at night.

Detailed explanation-2: -Deserts can be either cold or hot, although most of them are found in subtropical areas. Because of their extreme conditions, there is not as much biodiversity found in deserts as in other biomes. Any vegetation and wildlife living in a desert must have special adaptations for surviving in a dry environment.

Detailed explanation-3: -Tundra along the Colville River, Alaska. Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons.

Detailed explanation-4: -The four main types of desert include hot and dry deserts, semi-arid deserts, coastal deserts, and cold deserts.
