Deserts Around The World Map – A desert is usually considered a hot, dry place with lots of sand and dry soil. Although this is the case for some areas, not all fit this description. Rain, not sand and heat, is what determines desert areas. Deserts are found in all continents of the world but the nature and size of these deserts are very different. Since deserts are associated with extreme living conditions, they are often among the least populated areas in the world. In this article, we explore the largest desert in the world.
The Antarctic region is classified as a polar desert. With an area of 5.5 million square miles (14.2 km), it is the largest desert in the world. Unlike most of the world’s deserts, the Antarctic region spans an entire continent. In fact, an amazing 98 percent is covered with ice sheets. It is considered a desert because it receives an average of 10 millimeters of rain every year. Some experts even believe that some places far from the coast have not received rain in the last 14 million years.

Arctic tundra is the only remaining polar desert. It is widespread in many northern countries, including Canada, Greenland, Russia, and Asia. It is second only to Antarctica, with an area of 5.4 million square miles (13.9 million square kilometers). It is also considered a desert because of the lack of rain; The air was cold enough to hold moisture. Although it receives more rain than Antarctica, it still receives about six to ten inches per year.

The Sahara Desert is the largest desert in the world, covering 3.5 million square miles (9 million square kilometers). In eleven countries, it covers about a third of Africa. It is best known for its hot climate and the sand of the mountains, which are 183 meters high. Despite the harsh climate, it has many desert animals, including camels, lizards, and scorpions. There are few springs, but the Sahara has two rivers and twenty natural lakes.
Arabia is the second largest desert in the world. It covers most of the Arabian Peninsula in Asia, about 1.0 million square miles (2.6 million km). It is a barren and sandy place, but it is surprisingly rich in natural resources, such as oil and sulphur. Summer temperatures can reach fifty degrees Celsius during the day, but it drops significantly at night. Start with the beetles appearing in this dark place.
The Gobi Desert is the fifth largest desert in the world. Covering parts of Mongolia and China, it has an area of 0.5 million square miles (1.3 million square kilometers). Its location is rocky and rugged, making it an important trade route throughout history. Like any traditional desert, the Gobi experiences very hot and cold seasons. It is also considered as a rain shadow desert because the Himalayas block all the monsoons.
Located in Argentina, the Patagonian Desert—also known as the Patagonian Desert—is the sixth largest desert in the world. It has an area of about 0.26 million square miles (0.67 million square kilometers). To the west are the Andes, the highest mountain in the world, and to the east, the Atlantic Ocean. As a dry desert, it has the same characteristics as the Gobi desert. Frost covers the ground in winter, but the snow is not complete due to the drought of the region.

Great Victoria is a hot desert located in Australia. It is the seventh largest desert in the world, coming in at 0.25 million square miles (0.65 million square kilometers). It is a harsh place of sand, rocks, hard soil, and vegetation. In summer, the temperature rises to forty degrees. As with most tropical deserts, it is cold in the winter, but still hot. Grand Victoria receives an average of eight to ten inches of rain per year.
The Kalahari is a hot desert found in southern Africa. Encompassing parts of Namibia, Botswana, and South Africa, it is the eighth largest desert in the world at 0.22 million square miles (0.56 km). Interestingly, it is classified as a desert as it receives four to eight inches of rain per year, but twenty in certain wet years – ten more than is acceptable for the area to be consider the desert. Wild animals such as meerkat, hyena, kudu, and wildebeest call this area home.
At 0.19 million square miles (0.49 million square kilometers), the Great Basin is one of the “big four” deserts in North America. It spans many states, covering most of Nevada and Utah. The area north of the Mojave Desert is an arid climate of clay, clay, and sand; however, as a dry desert, it receives enough snow during the winter months. At 4,950 years old, the Bristlecone Pine is said to be the oldest living tree in the world.
The Syrian Desert – also known as the Syrian Desert or Jordan – is the tenth largest desert in the world, covering approximately 0.19 million square miles (0.49 km). It affects many countries in the Middle East, including Syria, Jordan, Saudi Arabia, and Iraq. Despite its name, it occupies more territory in Jordan than in Syria. Like a hot desert, it is an area without rocks and gravel. What animals could thrive in such conditions are now threatened by drought, grazing, and hunting.
How Are Deserts Formed? Why Are Deserts Hot?
Human-caused climate change is having a major impact on our world’s deserts. Melting ice is known to be shrinking the desert, but global warming is also causing increased desertification – the process by which fertile land becomes drier and drier. Pollution and other human activities are causing droughts and wildfires, as well as increasing soil salinity, which ultimately causes underground and desert areas to expand and heat up. Like the polar bear, this also harms local wildlife. Even animals such as lizards that used to thrive in such hot climates are struggling to spread to the desert.
Sahara is the best example to explain the above. A study conducted in 2018 showed that it has increased by ten percent since 1920. In general, deserts increase in the summer and decrease in the monsoon, but humans are interfering with this natural state. and they make the desert grow more than they shrink. . In fact, one-third of the desert’s current size is due to climate change.
About 33 percent of the world’s land is full of desert. Unless we change our ways, this number could increase significantly in the coming years. Lake Chad in a 2001 satellite image, with the original lake in blue. The lake lost more than 90% of its area between 1987 and 2005.
Desertification is a form of land degradation in dry areas where biological activity has been lost due to natural processes or human activities where fertile areas become dry.
How Do Deserts Form?
In geological history, the development of deserts is a natural phenomenon. In direct cases, the negative impact of human activities, inappropriate land management, deforestation and climate change on desertification is the subject of many scientific studies.
As recently as 2005, a great deal of controversy existed regarding the definition of the word “desert.” Helmut Geist (2005) identified more than 100 definitions. Most widely accepted
Among these is the Princeton University Dictionary which defines it as “the process of turning a fertile land into a desert usually as a result of deforestation, drought or poor agricultural practices”.
However, this initial understanding that desertification involves the expansion of physical desert has been abandoned as the concept progresses.

Desertification is defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as “land degradation in parts of the world that are dry and humid and caused by various factors, including climate change and human activity.”
There is also controversy over the categories of desertification, including, for example, the validity and usefulness of terms such as “man-made desertification” and “unstructured desertification”.
The world’s most famous deserts have been created by long-term climate processes. In most cases, deserts grow and shrink due to human activities. Paleodeserts are large sand seas that are now inactive because vegetation has settled them, some of which have extended to the edge of large deserts, such as the Sahara, the largest desert in the tropics.
Historical evidence shows that the great destruction of the land that happened many times ago in the arid regions has three parts: the Mediterranean, the Mesopotamia Basin, and the Loess Plain of China, where the population dse.

The first discussions on this topic originated immediately after the French colonialism in West Africa, where the Comité d’Etudes commissioned a study on the development of the desséchemt to conduct research on the prehistoric expansion of the Sahara desert.
It is estimated that about 10-20% of the dry areas have already been destroyed, the total area affected by desertification is 6 to 12 million square kilometers, about 1-6% of the country’s population lives in desert areas, and A. Billions of people are threatened by desertification.
