The largest hot desert in the world, northern Africa's Sahara, reaches temperatures of up to 122 degrees Fahrenheit (50 degrees Celsius) during the day. But some deserts are always cold, like the Gobi desert in Asia and the desert on the continent of Antarctica. Others are mountainous.nly about 10 percent of deserts are covered by sand dunes. The driest deserts get less than half an inch (one centimeter) of precipitation each year, and that is from condensed fog not rain. Desert animals have adapted ways to help them keep cool and use less water.
A desert is a region which receives very little rainfall. So generally there is only sparse vegetation. However more important is other factors like the temperature. The Sahara is the world's largest hot desert mainly just looks like lots and lots of sand.Antarctica on the other hand is a cold desert and is mainly covered in snow.So it's quite variable. As a side note the word desert can be used to describe an area of low or zero population, as in 'desert island'.he Sahara is the world's largest hot desert mainly just looks like lots and lots of sand.
