Chihuahuan Desert

                  Chihuahuan Desert is a desert, and an ecoregion designation, 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. 
                   The Chihuahuan Desert is higher in elevation than the Sonoran Desert to the west, mostly varying from 600–1,675 m (1,969–5,495 ft) in altitude. As a result, it tends to have a slightly milder climate in the summer (though usually daytime June temperatures are in the range of 35 to 40 °C or 95 to 104 °F). Winter weather varies from relatively mild to quite cold depending on altitude and the ferocity of northerly winds. Precipitation is somewhat more abundant than most of the southern Great Basin , the Sonoran, and Mojave deserts, however it is still usually less than 254 millimeters (10.0 in) per year.

Gobi Desert

             Gobi Desert (戈壁, Гоби) is a large desert region in Asia. It covers parts of northern and northwestern China, and of southern Mongolia. The desert basins of the Gobi are bounded by the Altai Mountains and the grasslands and steppes of Mongolia on the north, by the Hexi Corridor and Tibetan Plateau to the southwest, and by the North China Plain to the southeast. It had a surface of 1,295,000 km2 (500,002 sq mi). 
             Gobi is a cold desert, with frost and occasionally snow occurring on its dunes. Besides being quite far north, it is also located on a plateau roughly 910–1,520 metres (2,990–4,990 ft) above sea level, which contributes to its low temperatures. Average winter minimums are a frigid −40 °C (−40 °F) while summertime temperatures are warm to hot, with highs that range up to 50 °C (122 °F).

Great Victoria Desert

            The Great Victoria Desert is a sparsely populated desert area in Western Australia and South Australia. The Great Victoria is the largest desert in Australia and consists of many small sandhills, grassland plains, areas with a closely packed surface of pebbles (called desert pavement or gibber plains) and salt lakes. It covers an area of 424,400 square kilometres (163,900 sq mi) from the Eastern Goldfields region of Western Australia to the Gawler Ranges in South Australia. 
             Parts of the Great Victoria Desert are protected areas including Mamungari Conservation Park (formerly known as Unnamed Conservation Park) in South Australia, a large area of pristine arid zone wilderness which possesses cultural significance and is one of the fourteen World Biosphere Reserves in Australia. Habitat is also preserved in the large Aboriginal local government area of Anangu Pitjantjatjara Yankunytjatjara in South Australia and in the Great Victoria Desert Nature Reserve of Western Australia.

Arabian Desert

               Arabian Desert (صحراء عربية) is a vast desert wilderness stretching from Yemen to the Persian Gulf and Oman to Jordan and Iraq. It occupies most of the Arabian Peninsula, with an area of 2,330,000 square kilometers (900,000 sq mi). At its centre is the Rub'al-Khali, one of the largest continuous bodies of sand in the world. 
               The climate is extremely dry, and temperatures oscillate between extreme heat and seasonal night time freezes. It is part of the Deserts and xeric shrublands biome and the Palearctic ecozone. This ecoregion holds little biodiversity, although a few endemic plants grow here. Some typical plants are: Calligonum crinitum, Cornulaca arabica, Cyperus conglomeratus, Dipterygium glaucum, Limeum arabicum, Zygophyllum mandavillei.

Thar Desert

              Thar Desert (थार मरुधर, थार मरुस्थल, صحراےَ تھر, ٿر ريگستان), also known as the Great Indian Desert, is a large, arid region in the northwestern part of the Indian subcontinent and forms a natural boundary running along the border between India and Pakistan. With an area of more than 200,000 km2 (77,000 sq mi), it is the world's 18th largest subtropical desert. 
               There are eleven national parks in the Thar desert area, the largest of which are the Nara Desert Wildlife Sanctuary and the Rann of Kutch. There are a number of salt water lakes in Thar desert. These are Sambhar, Pachpadra, Tal Chhapar, Falaudi and Lunkaransar where Sodium chloride salt is produced from salt water.

Great Basin Desert

            Great Basin Desert is the largest U. S. desert. It is bordered by the Sierra Nevada Range on the west and the Rocky Mountains on the east, the Columbia Plateau to the north and the Mojave and Sonoran deserts to the south. Rainfall within the Great Basin Desert region varies from 7 - 12 inches of rainfall per annum. 
             The Great Basin Desert is a cold desert caused by the rain shadow effect of the Sierra Nevada to the west. The predominant flora are continuous shadscale and sagebrush. The ecotone demarcating the north of the Mojave Desert is the edge of Creosote Bush habitat and is also the south demarcation of the Great Basin shrub steppe and Central Basin and Range ecoregions. The ecotone is established by elevation increase, temperature decrease at higher elevations, and rainfall.

Sahara

             Sahara ( الصحراء الكبرى) is the world's hottest desert, the third largest desert after Antarctica and the Arctic. At over 9,400,000 square kilometres (3,600,000 sq mi), it covers most of North Africa, making it almost as large as China or the United States. The Sahara stretches from the Red Sea, including parts of the Mediterranean coasts, to the outskirts of the Atlantic Ocean. To the south, it is delimited by the Sahel, a belt of semi-arid tropical savanna that composes the northern region of central and western Sub-Saharan Africa. 
             The Sahara comprises several distinct ecoregions, and with their variations in temperature, rainfall, elevation, and soil, they harbor distinct communities of plants and animals. These ecoregions are: Atlantic coastal desert, North Saharan steppe and woodlands, Sahara desert ecoregion, South Saharan steppe and woodlands, West Saharan montane xeric woodlands, Tibesti-Jebel Uweinat montane xeric woodlands, Saharan halophytics, Tanezrouft. Some of the Saharian sand dunes can reach 180 metres (590 ft) in height.
