The following deserts are found in Africa: Kalahari, Namib, Chalbi, Danakil, Sahara, Tanzerouft, White Desert, Eastern Desert, Sinai Desert, Blue Desert, Atlantic Coastal Desert and Libyan Desert, which is also called the Western Desert. The deserts in Africa vary widely in size and location. Some, such as the Kalahari and Sahara, are vast stretches of hot and barren lands that cover significant portions of the African continent, while others, such as the Atlantic Coastal Desert, are considerably smaller.
Some deserts exist in individual countries while others cross national boundaries. The Kalahari, for instance, covers parts of Botswana, Namibia and South Africa. The Namib Desert, in contrast, resides in Namibia. Although they are different in size and physical characteristics, the Kalahari and the Namibia deserts exist close to each other on the African continent. The Kalahari covers approximately 360,000 square miles. It covers a large section of land in the interior plateau of southern Africa, extends across the Northern Cape province in South Africa, and combines with the Namib Desert in Namibia. The Kalahari, like many deserts, has a hot and dry climate. It consists primarily of sand dunes and gently undulating sandy valleys, which share an approximate average elevation of 3,000 feet above sea level. The Kalahari consists of three primary topographical features: sand sheets, dunes and vleis.
