Our Desert Facts will provide plenty of information about our planet's deserts. We will tell you here what you really should know about the deserts. First let's start with some basics!
The world’s coldest dry desert is located in Antarctica.
There is hardly any precipitation (rainfall, mist, fog, snow) in Antarctica, even rare snowfall turns into hard icy surface. There is almost no flora except for algae or mosses.
The Antarctic Desert is also the world's largest desert by area.
The Arabian Desert is located in Asia on the Arabian peninsula and covers large parts of Kuwait, Qatar, Saudi Arabia, the UAE, Jordan, Yemen, Oman, Iran and Iraq.
The centre of the desert is the Rub' al Khali, the so-called 'The Empty Quarter'.
The sand here has a red-orange colour and the terrain is covered mainly by sand dunes, some gravel plains and rocky plains.
The Aralkum Desert is known as the youngest desert of our planet.
This desert in Asia was formed by the former eastern basin of the Aral Sea in Uzbekistan. It formed in the 1960s when irrigation projects for the huge cotton plantations in the area drained the waters from the Aral lake.
By 2014, the eastern basin of the Aral Sea was completely dried up. This desert was created purely by poor environmental management and is seen as one of the worst environmental disasters.
The Atacama Desert in South America is situated on a plateau west of the Andes Mountains along the Pacific Ocean coastline.
This desert is known as the driest (non polar) desert in the world. Some parts of the region receive less than 2 mm/ 0.08 inches of precipitation every year.
The Atacama desert stretches over 1,600 km/ 1000 miles along the coastline along a narrow strip from Chile to Peru.
The Gobi Desert is located in eastern Asia and is the world’s largest (non polar) cold desert. This desert spreads from Mongolia to China. The Gobi desert is Asia's second largest desert after the Arabian desert.
Deforestation, overgrazing and water depletion are among the main reasons this desert is growing every year at an alarming rate.
Dust storms blow away topsoil and the desert turns many previously fertile areas into barren land. The Great Green Wall project aims to combat the desertification by planting 88 billion of fast growing trees in this desert. The world's largest artificial forest will stretch over 4,800 km/ 2,982 miles across northern China. Read more here.
The Mojave Desert is located in the USA, to the south of the Great Basin Desert and to the north of the Sonoran desert. The Mojave Desert is the driest desert on the North American continent.
Death Valley, one of the hottest spot in the world, is located in the Mojave Desert. Mojave comes from the Spanish word for 'place besides the water'. The largest city in the Mojave desert is Las Vegas with roughly 3 million people.
The Namib Desert is located in Southern Africa along the Atlantic Ocean coastline. The Namib has some of the highest dunes in the world with heights of over 300 m/ 980 ft. Read more here.
The Namib stretches from Angola through Namibia towards South Africa over 2,000 km/ 1,200 miles.
The coastal desert is also known as the oldest desert in the world. The salt and clay pans of Soussousvlei, a dried up lake, are a popular tourist attractions in Namibia's Namib-Naukluft national park as is climbing the tall dunes along the coastal town of Walvis Bay. Read more about Namibia here.
The Pinnacles Desert is located in Western Australia. The pinnacles in Nambung National Park are limestone pillars and some reach up to 3.5 m/ 11.5 ft in height. Wild emus can be found in this desert.
This desert is only a small Australian desert but is known for its scenic landscape. The largest desert in Australia, however, is the Great Victoria Desert, which is located further inland in Western Australia and South Australia.
The Sahara Desert is the world’s largest hot desert. It is also the hottest of all the deserts on our planet.
The Sahara Desert has grown more than 10% in the last century due to climate change and other natural climatic variations. A Great Green Wall project, similar to that in the Gobi Desert, has been started in the Sahara in 2007 to combat desertification.
The Sahara Desert covers most parts of North Africa and is similar in size to the land area of the USA or China. The word sahra in Arabic means 'desert'.
Huge rolling sand dunes as these in the Sahara desert are only found in about 10% of the world's desert areas. Most deserts consist of sandy or rocky soil or salt flats.
The Salar de Uyuni is a desert in South America that has been formed by salt crystallisation through water evaporation of a huge salt flat or playa. The word salar comes from the Spanish and means 'salt flat'. The salar is located in the Andes mountains at an elevation of over 3,656 m/ 11,995 ft.
This dried out salt pan once was part of a large prehistoric lake in the Altiplano of Bolivia. The salt flat covers more than 10,000 square kilometres/ 3,861 square miles and the Salar de Uyuni is known as the world's largest salt flat. The thick salt crust which contains more than 10 billion tonnes of salt.
When it rains the Salar looks like a huge mirror measuring 129 km/ 80 miles across. The salt flats are a breeding ground for pink flamingos.
The Deserto de Tabiernas, as they call it in Spanish, is Europe’s only desert area and located in Spain. The Tavernas are an semi-arid mountain region near Almería.
The high altitude of the region and the scenic landscape of this desert in Andalusia has been beneficial for film making. Many Western-style movies as well as one scene in the Game of Thrones series have been filmed in the Tabernas.
This desert stretches from eastern Pakistan to northwestern India. About 85% of the desert is located in India and most of it in India's largest state of Rajasthan.
The Thar Desert is also the world's most densely populated desert area. About 40% of Rajasthan's population live in the Thar Desert. Desert safaris around Jaisalmer are a popular tourist attraction.
The subtropical Thar Desert is home to many species of migratory and endemic birds.

About 25 million people live in the arid areas of Rajasthan. The annual desert festival in Jaisalmer attracts desert settlers in colourful traditional dress from near and far.
Desert Facts: Desert Vegetation
Most plants in the deserts are heat, drought and salt tolerant. Some plants store the water in their leaves, stems or roots. Some plants have very long roots to reach the ground water.
The Welwitschia plant in the Namib desert is one of these unique desert plants. They are considered among the oldest desert plants, as they are on average 500 - 600 years old, some are even 2000 years. Their normal lifespan is 400 - 1500 years! They never shed their leaves, they just grow and grow!
