Southern Arabian Peninsula
The two gulfs are connected by the Strait of Hormuz, in which Qeshm Island, belonging to Iran (top), can be found.
The country of Oman occupies most of the coastal area of this section of the peninsula. The al Jebel al Akhdar mountain ranges are to the North, along the Gulf of Oman. The central part of the country, however, is covered mostly by a vast gravel desert plain (light tan).
Encompassing a large area west of Oman’s gravel desert plain is the Rub’ al Khali (which translates as Empty Quarter), one of the largest sand deserts in the world.
With a total area of some 650,000 square kilometres (250,000 sq mi), it covers much of southern Saudi Arabia, as well as parts of Oman, the United Arab Emirates and Yemen.
The sands of the Rub’ al Khali near Saudi Arabia’s border with Oman and the United Arab Emirates are reddish-orange, and change to yellow then to tan as one moves westward.
