It is the largest sandy desert in the world. Located in the north of Africa, the climate conditions in this region are very harsh, and it is one of the most unsuitable places on earth for biological survival. “Sahara” is a transliteration of Arabic. In Arabic, “Sahara” is a great dessert, which originates from the language of the local nomadic Tuareg people, and originally means “great desert”.|
|2||Libyan Desert||The Libyan desert is located northeast of the Sahara desert. Including central and Western Egypt and eastern Libya. The Libyan desert is a plateau inclined from south to north, with an altitude of 350 ~ 500 meters in the south, 100 ~ 250 meters in the middle and North, and the highest terrain in the southwest, with an altitude of 1800 meters.|
|3||The Australian Desert||The Australian desert  is the largest desert in Australia, with an area of about 1.55 million square kilometers. It is the fourth largest desert in the world. It is composed of four parts: the great sand desert, the Victoria desert, the Gibson Desert, and the Simpson Desert. The maximum temperature in summer can reach 50 degrees Celsius. In 1973, an Australian botanist named Flannery found that there are about 3600 kinds of plants thriving and symbiotic in this desert while traveling by motorcycle, The discoverer called it a desert garden.|
|4||Arabian desert||The Arabian desert is located on the eastern edge of the Sahara desert in North Africa. Located in the east of Egypt, between the Nile Valley, Suez Canal, and the Red Sea, it is also known as the eastern desert. In the middle, there is the maaza plateau, in the East, there are isolated mountains such as shaibbanat mountain, Sibai mountain, and umnakat mountain, and in the south, it is connected with the Nubian desert of Sudan. Most of them are conglomerate deserts and exposed rock mounds with an altitude of 300 ~ 1000 meters. Cut by the East-West intermittent rivers talfa River, hudein River, and its tributaries and the North-South seasonal river kina River, it covers an area of 2.33 million square kilometers and is the second largest desert in the world.|
|5||Gobi desert||Gobi (Mongolian: Говь）， In Mongolian, it means desert, gravel desert, arid place, etc. The Gobi is one of the largest desert and semi-desert regions in the world, stretching across the vast land of northern East Asia and across the vast space of the Mongolian Plateau. Most areas of the Gobi are not deserts but bare rocks,|
The Gobi desert, also known as the great Gobi, covers an area of 1.3 million square kilometers. It is located between the people’s Republic of China and Mongolia. It is the northernmost desert in the world. It is located in Eastern Gobi Province, central Gobi Province, southern Gobi Province, Gobi Altai province, and other provinces in the south of Mongolia, as well as the Western Erlianhot area of Xilingol League in Inner Mongolia Autonomous Region of China. The two edges of the Gobi desert are called Monan Mobei respectively.
|6||Patagonia desert||The terrain of this area is mainly plateau and narrow coastal plain. The rivers originate from the Andes and flow eastward into the Atlantic Ocean, cutting into river valleys. However, due to the small local rainfall, most of the rivers belong to intermittent rivers, and there are many glacial landforms in the south, such as fjords. Under the influence of the Falklands cold current, Patagonia has a cold and dry climate, with an annual rainfall of 90-450 mm and an annual average temperature of 6-20 degrees. The colder it is in the South and the less rainfall it receives. Most areas form deserts, which are called Patagonia deserts. The Patagonia desert is located in Argentina in the south of South America and on the east side of the Andes. It covers an area of about 670000 square kilometers and is mainly composed of vast grasslands and deserts. Patagonia is generally east of the Andes in the Americas, mainly in Argentina, and a small part of it belongs to Chile.|
|7||Rubkhali desert||The rubkhari desert is roughly northeast-southwest, 1200 kilometers long and 640 kilometers wide, covering an area of 650000 square kilometers. It is red because it is rich in iron oxide. The altitude is 100-500 meters. In terms of morphology, it can be divided into East and West deserts. Among them, the eastern desert is 100-200 meters above sea level, mostly large sand dunes arranged in parallel. Some sand dunes are 300 meters high and 20 kilometers long, almost a sand mountain. Rubkhari desert (Arabic: الربع الخالي）， is the largest mobile desert in the world, named for its area accounting for about a quarter of the Arabian Peninsula. It is one of the largest deserts in the world, covering the entire southern region of Saudi Arabia and most of the territories of Oman, the United Arab Emirates, and Yemen. Also known as the Arabian desert.|
|8||Kalahari Desert||Kalahari desert also translated as Kalahari desert, is also known as the Kalahari basin. The inland dry region of Southern Africa. Also known as the “Kalahari basin”, it is the main topographic area in South Central Africa. The total area is about 630000 square kilometers. The longest part of the Kalahari desert is about 1600 kilometers from north to south, and the maximum distance from east to west is about 960 kilometers. Its area is estimated to be 930000 square kilometers.|

|9||Great Sandy Des.||Dasha Desert The Western Australian Desert Northern belt, mostly in Western Australia. Located south of the Kimberly Plateau, east of the Pilbara region, stretching to the east of the northern local border. Covering an area of about 410,000 square kilometers, most of the sand dunes, are only in the central rocky desert. Northern Desert, Western Australia. It starts from the 80 li beach on the Indian Ocean coast in the west, reaches to the north, and rises from the Gyeongbury Hills, the Tropic of Cancer, and the Gibson (Gibson) desert in the north. The range is roughly the same as that in the Ganning (Canning) basin. The vast desert has large salt marshes and sand dunes. There are 1,600 kilometers of cattle lanes from southwest to northeast through the desert. Australia has four great deserts, all found in the heart of the western plateau, namely, the Great Sand Desert, the Victoria Desert, and the Gibson Desert.|
|Located in the region located in the center of the Tarim Basin in southern Xinjiang, the Taklimakan Desert is the largest desert in China, the tenth largest desert in the world, and the second largest mobile desert in the world. The whole desert is about 1,000 kilometers long from east to west, covering an area of 330,000 square kilometers. The average annual precipitation is not more than 100 mm, and the lowest is only four or five mm, but the average evaporation is as high as 2,500 ~ 3,400 mm. Here, the pyramidal sand dunes stand about 300 meters above the plain. The wind can blow up the sand wall, up to three times its height. Sand dunes stretch in the desert, often moving by the wind. There are also a small number of plants in the desert, their roots are extremely developed, dozens of times or even hundreds of times more than the ground part, in order to absorb the water underground, where the animals have summer sleep phenomenon.|
