Gravel desert

Gravel desert is the name given to deserts that consist mainly of gravel. They arise after erosion of stone or rocky deserts (accumulation of coarser grain sizes by blowing out the finer grain sizes) or through the deposition of gravel in the run-up to glaciers. The surface of the desert type is covered with small pebbles and a few grains of sand.

Gravel deserts are found especially within the Sahara , where they are called Serir and make up 5% of the desert area. The gravel desert is a less common type of desert there than the rock and stone desert ( Hammada ) or the sandy desert ( Erg ). The Reg represents a special surface type of the gravel desert.

As for the desert, the vegetation is sparse, at least some wood and thistle plants survive. Gravel deserts are easy to traverse for vehicles and dromedaries .
