Q. Which country is famous for red sand?

Answer

Near Riyadh, Saudi Arabia, there is a region of red desert sand dunes known as Red Sand. It connects the Empty Quarter and the Nafud deserts, providing city people with their closest opportunity for desert exploration. The reddish tints of the sand are caused by the presence of iron oxide, and the desert itself spans 45,000 square kilometers, with peaks reaching elevations of 300 to 600 meters. About 200 kilometers north of Riyadh, the desert is home to what are arguably the most magnificent dune formations in the province: a series of star-shaped mounds.
