These areas are known as desert pavements, and little further erosion takes place. Other desert features include rock outcrops, exposed bedrock and clays once deposited by flowing water. Temporary lakes may form and salt pans may be left when waters evaporate.

Dry river beds are a common sight in many deserts, and are called wadis in some African and Middle Eastern deserts. Some rainfalls may bring torrents of 5 to 10 cm of rain in a few hours, leading to flash flooding in ravines or canyons, a seemingly paradoxical occurrence in the driest places on Earth.

A rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather. On the other side of the mountain—the rain shadow side—all that precipitation is blocked. In a rain shadow, it’s warm and dry.

As the air rises, it cools and drops its moisture as heavy tropical rains. The resulting cooler, drier air mass moves away from the Equator. As it approaches the tropics, the air descends and warms up again. The descending air hinders the formation of clouds, so very little rain falls on the land below.

Some deserts are near the equator where the air is very dry. Some deserts are in the middle of a continent. By the time the wind gets there, it has little moisture. If rain falls it stays dry in deserts because the sand absorbs the water.
