  2. A desert is a place with 10 inches or 25cm of rain or less a year.  Deserts cover about one seventh of the earth's surface.     The landscape of deserts vary greatly; but all deserts have 1 thing in common . They are all extremely dry, and can be one of the harshest places on earth .     Many deserts have extremes in temperature, with very high temperatures in the day and cold temperatures at night . Deserts are not only made of sand as many people think.  They  consist of rocks, mountains, and sand. Desert sands are often rock which has weathered down to sand over the centuries. There are 3 main ways in which a desert can be made. Deserts are formed because of lack of water. 1) Arid or dry regions are  caused by not being near a large body of water. 2) Inland areas lack moisture from the air. 3) Mountains may prevent rain from reaching areas making the areas dry and after awhile a desert.     There are many deserts on the earth's surface. What is a desert?

Not all desert area don’t have rainfall , occasionally rainfall can turn some areas of desert into pockets of green areas . Today vast areas of desert are green as a result of pumping water from deep bore wells.
