Every 20,000 years, the Sahara Desert, which is now parched, transforms into a huge sea of rich savanna grassland. This occurs as a result of the Earth's rotation around the sun, altering the position of the North African Monsoon. If you're like that kind of thing, mark your calendarâthe next time the Sahara turns green will be around 15,000 years from now. The Sahara Desert is the world's third biggest desert, covering about 3,300,000 square miles. It is about the size of the United States, including a considerable portion of North Africa, and is the world's biggest hot desert.
Antarctic Desert Map
Antarctica is considered a polar desert. It is the world's biggest desert, covering 5.5 million square miles (14.2 million square kilometers). Unlike the majority of the world's deserts, the Antarctic occupies the whole continent. Indeed, an astounding 98 percent of the land is permanently covered in ice. It is classified as a desert since it receives an average of just 10 millimeters of rain each year. According to some researchers, some areas distant from the shore have not seen rain in the last 14 million years.
The Great Victoria Desert ecoregion in southern Australia is a desolate, dry, and sparsely populated desert. It is located inside South Australia and Western Australia and is made up of several tiny sandhills, meadows, and salt lakes. It spans more than 700 kilometers (430 miles) in width (west to east) and covers an area of 424,400 square kilometers (163,900 sq mi). The Western Australia Mallee shrub ecoregion is bounded on the west by the Little Sandy Desert, on the northwest by the Gibson Desert and the Central Ranges xeric shrublands, on the east by the Tirari and Sturt Stony deserts, and on the south by the Nullarbor Plain.

Apart from camels and goats, oases and the edges of rivers and lakes are home to a diverse array of desert plants. For millennia, figs, olives, and oranges have thrived in desert oasis. Certain desert regions depend on resources trucked in from more fruitful partsâfood trucked in from distant farmlands or, more commonly, water piped in from wetter places. Large expanses of desert land are irrigated with water extracted from subsurface sources or transported by canal from distant rivers or lakes. The prosperous Inland Empire of southern California is comprised of two deserts (the Mojave and the Sonoran) that depend on water for agriculture, manufacturing, and residential development. Canals and aqueducts provide water to the Inland Empire from the Colorado River to the east and the Sierra Nevada snowmelt to the north through canals and aqueducts.

5.500,000 square miles in Antarctica Antarctica is situated in the southern hemisphere and is covered by an ice sheet of around 7.1 million cubic miles and measuring approximately 1.5 miles thick. Antarctica is the driest location on the globe, with a humidity rating of 5%, and is hence regarded as a huge barren cold desert.
Although the limits of the Great Basin Desert are somewhat ambiguous, most people agree on one thing: it is the biggest desert in North America, even if its exact size is unknown. As with the South American deserts, the Great Basin Desert was formed by the Rocky Mountains' rain shadow. This desert, which covers the majority of Nevada and extends into California, Idaho, and Utah, is notable for its severe temperatures, with daily highs surpassing 32°C (90°F) and nightly lows as low as 4°C (40°F). Summers are hot and dry, but winters are very cold and snow-covered, owing to the presence of icy alpine ranges. Although temperatures in the neighboring Mojave and Sonoran deserts may be more harsh, the Great Basin Desert's more âmoderateâ climate is due to its elevation: there are up to 33 peaks that surpass 3,000 meters (9,800 feet)! Desert of Arabia
In 2011, odd zigzag patterns in the Gobi were discovered in Google images, sparking a flurry of conspiracy theories, including one involving aliens. However, the lines were most likely used to calibrate Chinese spy satellites in order to assist the spacecraft in orienting itself in orbit, according to Jonathon Hill, a research technician and mission planner at Arizona State University's Mars Space Flight Facility. Additionally, the Gobi is an excellent location for dinosaur hunting. In 2012, a rare Tyrannosaurus Rex skeleton unearthed in that area was auctioned off for $1 million to settle a legal issue.
Top 5 of 2010 research on anything.
The data represents the world's top five biggest hot deserts and excludes cool deserts. If we add cold deserts, the Antarctic polar desert would rank first on our list at 14,000,000 km2, while the Arctic desert would rank second at 13,700,000 km2. Additionally, this list does not include desert complexes (deserts comprised of multiple deserts), such as the Australian and Arabian deserts. The data is expressed in square kilometers. Please note that several of the world's major deserts are often subdivided into smaller desert areas by geographers.

This vast region in northern Chile is famous for a variety of reasons. To begin, the Atacama Desert is recognized as the world's driest area. The Atacama Desert is sandwiched between two mountain ranges â the Andes and the Chilean Coastal Ranges â and is surrounded by a double-rain shadow, preventing it from receiving rainfall from either the Pacific or Atlantic Oceans. The Atacama has been dry for at least 3 million years (if not longer), making it the world's longest continually dry location. Between 1590 and 1971, there seems to have been no major rainfall in the Atacama. Annual rainfall is around 15 mm these days (0.6 inches). The Atacama Desert has long been likened to Mars, and film and television companies have been known to shoot Martian scenes here. NASA researchers have also conducted tests in the Atacama.
Others, such as Mongolia's Gobi and China's Takla Makan deserts, are just too far from the ocean for the winds to retain any moisture long before reaching the far continental interior, even what little moisture remains in the Indian-born clouds after they scrape over the rocky Himalayas.
Aridity's Causes
Deserts of the World - Map Quiz Game: Deserts are predominantly found in two latitude areas on the globe. Tropical air carrying moisture steadily cools and drops its moisture in the form of rain as it moves north and south from the equator. As the air continues to flow away from the equator, the majority of its moisture is lost, and by the time it reaches the... 108 times seen

5 Largest Deserts In The World
Even if the desert, in our perspective, is nothing more than a collection of sand, the Australian desert is unique. There are both sandy and stone deserts here, the latter of which is completely coated with fine gravel. Additionally, the Australian Desert is well-known for the Simpson Desert's crimson dunes. Some of them reach a height of up to 40 meters. 5. Arabian Desert (2.3 million square kilometers)

The Gobi Desert, the world's fifth biggest, is located in northern/northwestern China and southern Mongolia. While both nations value the Gobi, this central Asian desert is more renowned for its association with Mongolian history and culture. Mongolian tradition has it that the Gobi Desert was constructed when a Mongolian chief employed wizardry to evade the Chinese armies.
The Desert Ecosystem The majority of people see a desert as a terrain covered with sand and sand dunes. Although many deserts are coated with sand, the majority are not. Numerous desert landscapes consist of stony surfaces. They are rocky because to the rapid evaporation of any sand-sized or smaller particles on the surface. Rocky deserts are wind-swept wasteland environments. Because most deserts get so little precipitation, surface streams often flow only soon after rainfall - unless the stream has an outside supply of water. Streams that enter a desert often experience significant water loss before they escape. Evaporation removes some of the water. Some is lost as a result of transpiration (taken up by plants and then released to the atmosphere from the plants). Additionally, some are lost to infiltration (water soaking into the ground through the bottom of the stream channel). ADVERTISEMENT
Climate change caused by humans is having a devastating effect on the world's deserts. While it is well accepted that melting ice caps are diminishing the polar deserts, global warming is also increasing the pace of desertificationâthe process by which productive land becomes parched and barren. Pollution and other human activities are generating droughts and wildfires, as well as increasing the amount of salt in the ground, which eventually results in the expansion and warming of subtropical and semiarid desert areas. As with polar bears, this has a detrimental effect on nearby animals. Even creatures that thrive in these sorts of hot habitats, such as lizards, are suffering with desertification. The Sahara Desert is the finest illustration of the preceding. According to a 2018 research, it has increased by 10% since 1920. Deserts expand in size during the dry season and shrink during the rainy season, but people have disrupted this natural cycle, leading deserts to grow faster than they shrink. Indeed, climate change is responsible for a third of the Saharaâs present extent.
