This is a list of the largest deserts in the world by area. It includes all deserts above 50,000 km 2 (19,300 sq mi). Some of Earth's biggest non-polar deserts.
The Atacama Desert (Spanish: Desierto de Atacama) is a desert plateau located on the Pacific coast of South America, in the north of Chile.Stretching over a 1,600-kilometre-long (1,000-mile) strip of land west of the Andes Mountains, it covers an area of 105,000 km 2 (41,000 sq mi), [2] which increases to 128,000 km 2 (49,000 sq mi) if the barren lower slopes of the Andes are included.
Nefud Desert – a desert in northern part of the Arabian Peninsula. Ramlat al-Sab`atayn – a desert in north-central Yemen. Wahiba Sands – a desert covering great parts of Oman. Aerial view of Negev. Judaean Desert – a desert in eastern Israel and the West Bank. Negev – a desert located in southern Israel.
The world's largest non-polar deserts. Deserts occupy about one third of Earth's land surface. [6] Bottomlands may be salt -covered flats. Eolian processes are major factors in shaping desert landscapes. Polar deserts (also seen as "cold deserts") have similar features, except the main form of precipitation is snow rather than rain.
Desert climate. The desert climate or arid climate (in the Köppen climate classification BWh and BWk) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall ...
The Sahara (/ s ə ˈ h ɑːr ə /, / s ə ˈ h ær ə /) is a desert spanning across North Africa.With an area of 9,200,000 square kilometres (3,600,000 sq mi), it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.
It is one of the driest places on Earth, [2] though there are several anecdotal accounts of rainfall within the Dry Valleys. [3] [4] The region is one of the world's most extreme deserts, and includes many features including Lake Vida, a saline lake, and the Onyx River, a meltwater stream and Antarctica's longest river.
Tropical heat generates unstable air in this area, and air masses become extremely dry due to the loss of moisture during the process of tropical ascent. [1] Hadley cell above Sahara desert. Another significant determinant of tropical desert climate are Hadley cells. Hadley cells concentrate all precipitations in the hotter humid lower pressure ...
