Deserts usually have low humidity and few clouds that would slow heating so they receive the full effect of solar heating.
It is the feeze/thaw cycle that makes frost wedging really effective as an erosive force. Desert areas that are warm during the day and freezing at night experience more wedging than permafrost areas.
There are 26 major desert areas around the world, each with its own climate data. There are hot deserts, there are cold deserts and there are cool deserts. You need to specify a particular desert.
Bilbies keep cool in the desert via a number of special features. They have large ears for thermo regulation. Blood flows quickly into the thin tissue around the Bilby's ears, preventing them from getting too hot during the day and from losing body heat quickly at night. Bilbies also dig burrows enabling them to keep cool during the heat of the day, but warm on cold nights.
The Antarctic desert is a polar desert, and is not 'warm' at all. Antarctica is the coldest continent on earth.
cold desert
i think deserts cool off FAST during night, so somewhere warm
one - fifth
Salinity is increased during time.
While the Namib Desert is classified as a 'cold desert,' is is still quite hot inland from the coastal regions so the gazelle would have no problems staying warm. They might, however, have problems witht he heat. Even the cooler coastal areas are really just cool and not really cold.
During the day, the sun heats the desert - making it extremely hot. At night, the heat simply dissipates.
The Chihuahuan Desert is huge and temperatures depend upon the specific location and season of the year. Temperatures in some areas in the summer can reach or even exceed 115 degrees F. In the winter temperatures may drop into the 30s or even 20s (degrees F) at night but usually warm into the 50s and 60s during the day. It is considered a hot subtropical desert.
Deserts generally have low humidity and little cloud cover. The lack of these two factors allows the surface to warm quickly when the sun comes up. In the evening the lack of humidity and cloud cover allow the heat to quickly radiate back into space, cooling the desert.
