Random Sand Fact
The world’s largest continuous sand desert lies mostly in Saudi Arabia.
Rub al-Khali, the Empty Quarter, stretches across Saudi Arabia, Oman, the United Arab Emirates and Yemen. Nearly four fifths of it lies in Saudi Arabia, where some dunes rise more than 200 metres above the surrounding ground.
Beneath the sand are traces of a very different landscape. Ancient lakebeds, stone tools and animal fossils show that parts of the region once had lakes, vegetation and far more water than today.
