DIFFERENT DESERT LANDSCAPES~

Landscapes of deserts are generally divided into five groups: sand, stony, rock, plateau and mountain. Though all deserts are covered with sand, weather a lot or little, but this does not mean that all deserts are sand deserts.

SAND DESERTS are not only defined for their vast areas of sand, but also for the numerous linear dune systems they have.

STONY DESERTS are also called 'serir' in Egypt, they have comparitavely level gravel surfaces.

But ROCKY DESERTS are different, they usually have bare rock surfaces, and huge pavements clear of sand and gravel.

PLATEAU DESERTS which are also named 'mountain-and-bolson deserts' or 'badlands', are dominated by rocky plateaus, often cut apart by river channels which contain rain water.

As for MOUNTAIN DESERTS, they are bare and arid orders or jaggedy rock peaks. These mountains include the Tibesti and Ahaggar ranges of Sahara, the ranges of Sanai, and also the Macdonnell mountains in central Australia.
