In this world, there are thousands of Deserts but to mention just few that are the 10 Largest Deserts in the World and they are as follows;

They are formed by weathering processes because of large temperature differences between day and night cause stress on the rocks that consequently break into pieces.

Although rain is rare in deserts, there are occasional showers that can result in sudden flooding. Rain falling on hot rocks can cause them to fall apart and the resulting fragments and debris that is scattered over the desert floor are further eroded by the wind.
It can be classified by the amount of precipitation that falls, by the prevailing temperature, by the causes of desertification, or by their geographical location.

1. Great Basin Deserts

Great Basin

The Great Basin Desert is part of the Great Basin between the Sierra Silver State and also the Wasatch vary. The desert is a geographical region that largely overlaps the steppe of the Great Basin shrub, It covers an area of approximately 190,000 square miles.
This dessert is one of the temperate deserts with hot and dry summers and snowy winters. The desert covers a large part of the state of Nevada and extends to western Utah, Eastern California and Idaho.

The desert is among the top 10 largest deserts in the world and one among the four biologically defined deserts in North America, additionally to the Mojave, Sonoran and Chihuahuan deserts.

2. Syrian Desert

10 largest deserts in the world

The Syrian desert is also part of the 10 largest deserts in the world and also known as the Syrian steppe, the Jordanian steppe or the Badia, is a region of desert, semi-desert and steppe with an area of 500,000 square kilometres (200,000 square miles) from the Middle East, including parts of Southeast Syria, Northeast Jordan, North Saudi Arabia and Western Iraq. It accounts for eighty-fifths of the surface area of Jordan and fifty-fifth of Syria. In the south, it borders and becomes the Arabian desert. The land is open, rocky or gravely desert paving.

The desert is bordered by the Orontes Valley and the volcanic field of Harrat al-Shamah in the west and by the Euphrates in the east. In the north, the desert gives way to the more fertile lawns and in the south, it ends in the deserts of the Arabian peninsula.

3. Patagonian Desert

Patagonian Desert

This is the largest desert in Argentina and is the eighth largest desert within the world per space. It covers a region of 673,000 square kilometres, mainly located in Argentina and is bordered by the Andes in the west and the Atlantic Ocean in the east, in the Patagonia region, in southern Argentina. In the north, the desert sorts into the Cuyo region and the Pampas.

The central parts of the steppe are dominated by bushy and herbaceous plant species, although in the west, where the precipitation is higher, bushes are replaced by grasses. Topographically, the deserts consist of alternating plateau and massifs dissected by river valleys and canyons. The more western parts of the steppe are home to lakes of icy origin and merge into bare mountains or cold temperate forests along valleys. It is a cold desert with temperatures that rarely exceed 12 degrees Celsius.

4. Kalahari Desert

10 largest deserts in the world

The Kalahari Desert could be a giant semi-arid sandy savannah in South Africa that spans 900,000 sq. kilometers (350,000 sq. miles) and covers a lot of Botswana, parts of Namibia, and regions of South Africa.
A semi-desert such as the Kalahari desert with huge pieces of excellent grazing after a good rainfall, the Kalahari supports more animals and plants than a real desert, such as the Namib desert in the west.

There is a small amount of precipitation and the summer temperature is very high. The driest areas usually receive 110 – 200 millimetres of rain per year, and the wettest just over 500 millimetres (20 in). The surrounding Kalahari Basin covers over 2,500,000 sq. kilometers and extends further to Botswana, Namibia and Republic of South Africa and penetrates parts of Angola, Zambia and Zimbabwe.

5. Gobi Desert

10 largest deserts in the world

This is a large desert or lame area in Asia. It includes parts of North and Northeast China and South Mongolia. The desert basins of the Gobi Desert are bordered by the Altai Mountains and therefore the grasslands and steppes of Mongolia within the north, by the Taklamakan desert in the west, by the Hexi Corridor and the Tibetan plateau in the southwest and by the North China Plain in the southeast. The Gobi is remarkable in history as part of the great Mongolian empire and as the location of several important cities along the Silk Road.

The Gobi measures more than 1600 km from southwest to northeast and 800 km from north to south. The desert is widest in the west, along the line that connects Lake Bosten and Lop Nor. It covers an arc of land 1,295,000 km2 in the area from 2007; it is the sixth-largest desert in the world and the second-largest in Asia. Much of the Gobi is not sandy but has exposed rock.

6. Arabian Desert

Arabian Desert

The Arabian Desert is a vast desert in West Asia. It extends from Yemen to the Persian Gulf and Oman to Jordan and Iraq. It covers the majority of the Arabian Peninsula, with an area of 2,330,000 square kilometres (900,000 square miles). The Arabian Desert is the fourth largest desert in the world and also the largest in Asia. In the middle is Ar-Rub al-Khali (the empty neighbourhood), one of the largest continuous sand bodies in the world.

The climate is mostly dry (the majority receives around 100 mm (3.9 in) of rain per year, but some very rare places only receive 50 mm), and temperatures fluctuate between very high heat and seasonal night frost freezes. It is part of the deserts and xeric shrubland biomes and the Palearctic ecozone.

7. Australian Desert

Australian Desert

Australia Desert is classified as the fourth out of the 10 largest deserts in the world largest desert category, covering 1,371,000 square kilometres (529,000 square miles), or nearly 18% of mainland Australia. However, around 35% of the Australian continent receives so little rain that it effectively becomes desert-like.

The deserts in Australia are mainly spread over the western plateau and the interior of the country. No weather station in a dry region registers less than 100 mm average annual rainfall. The deserts of Australia, especially inland, lack significant summer rains.

8. Sahara Desert

10 largest deserts in the world

Sahara is a desert on the African continent. This happens to be the largest hot desert in the world. The area of 9,200,000 square kilometres is comparable to the area of China or the United States.
The desert covers a large part of North Africa, except the fertile region on the Mediterranean coast, the Atlas Mountains of the Maghreb and the Nile Valley in Egypt and Sudan.

It stretches from the Red Sea in the east and the Mediterranean Sea in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. The sky is mostly clear above the desert and the duration of the sunshine is extremely high everywhere in the Sahara. The majority of the desert has more than 3,600 hours of bright sun per year (more than 82% of daylight hours), and a large area in the eastern part has more than 4,000 hours of bright sun per year (more than 91% of daylight hours).

9. Arctic Desert

Arctic Desert

The ecoregion of the Arctic desert is a terrestrial ecoregion that covers the island groups Svalbard, Franz Josef Land, Severny Island and Severnaya Zemlya in the Arctic Ocean, above 75 degrees north latitude. The islands are covered with glaciers, snow and bare rocks in a harsh environment.

The temperature rises above freezing for a short time in the summer, so some ice melt occurs and the area supports colonies of seabirds and mammals. The Arctic Desert is the second among the 10 largest deserts in the world, covering 13,726,937 square kilometres.

Another diverse feature of this second largest desert in the world is that it is home to the people or animals that have adapted to the harsh conditions of thousands of years and 700 plant species and about 120 animal species, including arctic foxes, polar bears, wolves, squirrels, arctic hares, voles, lemmings, caribou, seals, walruses and whales.

10. Antarctic Desert

10 largest deserts in the worldThis is the largest Desert in the Earth’s southernmost continent and even in the world. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,200,000 square kilometres, it is the fifth-largest continent and nearly twice the size of Australia. At 0.00008 people per square kilometre, it is by far the least densely populated continent.

About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.

Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Most of Antarctica is a polar desert, with annual precipitation of 20 cm (7.9 in) along the coast and far less inland.
