Rub Al Khali

 

a sandy desert on the southeastern Arabian Peninsula, in a tectonic depression between mountains extending along the western, southern, and eastern seacoasts of the peninsula. Area, approximately 650,000 sq km.

The Rub al Khali, one of the world’s largest deserts, is a plain with elevations from 100–200 m in the east to 500–1,000 m in the west. Approximately 80 percent of the territory is covered by moving sands forming barchans (up to 150–200 m high), ridges, and individual massifs. In the east there are vast salt marshes; in places there are rocky plains. The annual precipitation reaches less than 50 mm per year; frequently there is no precipitation for several years in succession. There is no permanent surface run-off, and the ground waters are deep. In the sections not covered by sands there may be gypsum and limestone crusts. Vegetation grows primarily in the low areas between sand ridges (camel thorn, saltworts). The population, consisting mostly of Arabs, is nomadic and is engaged in camel raising. There are occasional oases on the outskirts of the Rub al Khali.
