1. Sahara Desert, North Africa: The Sahara is the world’s largest desert. At over 9,000,000 square kilometers (3,500,000 sq mi), it covers most of Northern Africa, making it almost as large as the United States or the continent of Europe. The desert stretches from the Red Sea, including parts of the Mediterranean coasts, to the outskirts of the Atlantic Ocean.
2. Arabian Desert, peninsula: Arabian Desert or Eastern Desert, c.86,000 sq mi (222,740 sq km), E Egypt, bordered by the Nile valley in the west and the Red Sea and the Gulf of Suez in the east. It extends along most of Egypt’s eastern border and merges into the Nubian Desert in the south. The Arabian Desert is sparsely populated; most of its inhabitants are based around wells and springs. Today most of the desert can be accessed by roads.
3. Gobi Desert, Mongolia / N.E China:The Gobi is a large desert region in Asia. It covers parts of northern and northwestern China, and of southern Mongolia.

4. Kalahari Desert, Southern Africa:The Kalahari Desert is a large arid to semi-arid sandy area in Southern Africa extending 900,000 square kilometers (350,000 sq), covering much of Botswana and parts of Namibia and South Africa, as semi-desert, with huge tracts of excellent grazing after good rains. The Kalahari Desert is the southern part of Africa, and the geography is a portion of desert and a plateau. The Kalahari supports some animals and plants because most of it is not a true desert.
5. Patagonia Desert, Argentina: The Patagonian Desert, also known as the Patagonia Desert or the Patagonian Steppe, is the largest desert in America and is the 7th largest desert in the world by area, occupying 260,000 square miles (673,000 km).

7. Great Basin Desert, USA:The Great Basin is the largest watershed of North America which does not drain to an ocean. Water within the Great Basin evaporates since outward flow is blocked. The basin extends into Mexico and covers most of Nevada and over half of Utah, as well as parts of California, Idaho, Oregon and Wyoming. The majority of the watershed is in the North American Desert ecoregion, but includes areas of the Forested Mountain and Mediterranean California ecoregions.
8. Chihuahuan Desert, Mexico:The Chihuahuan Desert is a desert that straddles the U.S.-Mexico border in the central and northern portions of the Mexican Plateau, bordered on the west by the extensive Sierra Madre Occidental range, and overlaying northern portions of the east range, the Sierra Madre Oriental.
