Deserts of the world: Namib
May 10, 2006 - 02:58 PMThe parched Namib Desert (less than 0.4 inches of rain annually) is home to the highest sand dunes in the world, blown into razor-sharp ridges by the wind. [Click thumbnail photo to enlarge.]
Namib means "enormous" in the Nama language: this desert stretches 1,200 miles along the Atlantic coast of Namibia, extending into Angola and South Africa. It is considered to be the oldest desert in the world, having endured arid or semi-arid conditions for at least 80 million years.
