Sahara Desert - November 16th, 2009

The Sahara is the world’s largest hot desert. At over 9,000,000 square kilometres (3,500,000 sq mi), it covers most of Northern Africa, including huge parts of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia. The area visible here includes southern Libya (upper left), northern Chad (lower left), southern Egypt (top right) and northern Sudan (bottom right).

The desert landforms of the Sahara are shaped by wind or by occasional rains, and include sand dunes and dune fields or sand seas, stone plateaus, gravel plains, dry valleys and salt flats. Several deeply dissected mountains and mountain ranges rise from the desert, many of which are volcanic, including the Tibesti Mountains, identifiable here as a brown area along the left edge.

The Tibesti Mountains are a group of dormant volcanoes forming a mountain range in the central Sahara desert in the Bourkou-Ennedi-Tibesti Region of northern Chad. The northern slopes extend a short distance into southern Libya. Here, some whitish colored dust can be seen blowing to the southwest, below the mountain range.
