In North Africa and the Arabian Peninsula there are deserts where very little rain falls. In this region temperatures even in the shade rise to 100˚ F. (38˚ C) and sometimes can go as high as 120˚ F. (49˚ C), about the same as a very hot bath. The sand and stones in direct sunlight are hot enough to burn you if you touch them.
Deserts have almost no rainfall. But deep inside the earth underground rivers sometimes flow. People in the desert must dig deep wells to reach this water or they must find special places where the water has come to the surface. Such a place is called an oasis.
