Sahara Desert - Saudi Arabia

The Arabian Peninsula is a plateau composed of crystalline rock overlain with sediments. Arabia is bordered on all sides by a series of escarpments. Summer temperatures average more than 100deg F(38deg C). More than one-fifth of the Arabian Peninsula is covered by the Rub al-Khali, which translates to "The Empty Quarter". The Rub al-Khali is the largest continuous sand body on the planet. Sand ridges hundreds of miles long, and sand mountains are common features of its landscape. Many of these dunes are well over 500 feet in height. Although symbolic of deserts, dunes are actually exceptional and cover less than 10 per cent of the Sahara desert.
