What is the largest desert in the world by area, and why?
The largest desert in the world by area is the Antarctic Desert. While it may be surprising to think of Antarctica as a desert, it is defined by high temperatures and low precipitation. Antarctica, the driest and windiest continent on Earth, receives very little rainfall. Antarctica is classified as a cold desert.
The extreme cold temperatures in Antarctica result in low humidity, which means very little moisture in the air. Most precipitation falls in snow, and the climate is harsh and arid. These conditions make Antarctica the largest desert, surpassing hot deserts like the Sahara in terms of area.
The Antarctic Desert covers an area of approximately 14 million square kilometres (about 5.4 million square miles), making it significantly more significant than other deserts worldwide. Despite its vast size, Antarctica remains one of the least hospitable and least inhabited places on the planet.
Desert is classified as an area devoid of vegetation and, to some extent, the precipitation it receives. Based on this classification, the world’s largest deserts are:
- Antarctic desert – 14,200,000 sq km located in Antarctica
- Arctic desert – 13,900,000 sq km located in the Arctic
- Sahara desert – 9,100,000 sq km located in Africa
- Arabian desert – 2,600,000 sq km located in the Middle East
- Gobi Desert – 1,300,000 sq km located in Asia
What is the largest desert in the world, and why is it considered a desert?
The largest desert in the world by area is Antarctica. While people often associate deserts with hot, sandy environments, a desert is technically defined by its low precipitation levels. Antarctica meets this criteria, receiving very little rainfall, and its frigid temperatures contribute to its classification as a cold desert.
The largest desert in the world is the Antarctic Desert. While deserts are often associated with hot, sandy environments, a desert is technically defined by its low precipitation levels, not its temperature. The Antarctic Desert covers the continent of Antarctica, and it is the driest and windiest desert on Earth.
Here are some key reasons why the Antarctic Desert is considered a desert:
- Low Precipitation: The definition of a desert is based on aridity, which is determined by the amount of precipitation a region receives. Antarctica is extremely dry, receiving very little rainfall. Much of the precipitation in Antarctica falls in the form of snow.
- Cold Temperatures: Although deserts are commonly associated with high temperatures, cold deserts also exist. Antarctica is the coldest place on Earth, with temperatures regularly dropping below freezing. The low temperatures contribute to preserving snow and ice, further limiting liquid water availability.
- Polar Desert Conditions: Antarctica is classified as a polar desert because it exhibits desert-like characteristics despite its opposite location. The cold air in polar regions holds less moisture, leading to low humidity and limited precipitation.
- Harsh Winds: Antarctica experiences katabatic solid winds and downslope winds that can further enhance evaporation and sublimation, contributing to the arid conditions.
- Snow and Ice Accumulation: Although it may seem counterintuitive, the accumulation of snow and ice in Antarctica contributes to its desert status. The continent’s vast ice sheet stores most of the Earth’s freshwater, and the dry conditions prevent the accumulation of liquid water necessary for vegetation to thrive.
In summary, the Antarctic Desert is the largest in the world due to its meagre precipitation, cold temperatures, polar location, harsh winds, and the dominance of snow and ice. Deserts can take various forms, and Antarctica is an example of a cold desert with unique environmental conditions.

Which one is the largest desert in the world?
The Antarctic Polar Desert, which makes up the vast majority of Antarctica, is the largest in the world. This single desert is larger than the combined size of the Gobi Desert, the Arabian Desert, and the Sahara Desert. Antarctica is the coldest, windiest, and most isolated continent on Earth. It is a desert because its annual precipitation can be less than 51 mm in the interior.
depends on how you define “desert”! There are two contenders for the title of largest desert in the world:
1. Antarctic Desert: Covering a whopping 14.2 million square kilometers (5.5 million square miles), the Antarctic Desert is the undisputed champion in terms of sheer size. This frigid expanse encompasses most of the Antarctic continent, receiving incredibly low amounts of precipitation (less than 200 millimeters annually) and experiencing freezing temperatures.
2. Sahara Desert: If we focus on hot, arid deserts (the traditional image of a desert), the Sahara takes the crown. At 9.4 million square kilometers (3.6 million square miles), it’s the Earth’s largest hot desert, stretching across multiple African countries. Despite receiving some rainfall in certain areas, the Sahara still boasts long periods of drought and scorching temperatures.
Therefore, the answer depends on what type of desert you’re considering. If we’re talking total area, regardless of climate, the Antarctic Desert reigns supreme. But if we’re focusing on scorching sand and hot winds, the Sahara Desert holds the title.
Both deserts are unique and fascinating ecosystems, showcasing amazing adaptations of life to extreme environments.
What is the largest desert in the world by area, and is it not sandy?
The largest desert in the world by area, which is not a sandy desert, is the Antarctic Desert. While many people associate deserts with hot, sandy environments, a desert is defined by its low precipitation levels.
Antarctica is considered a desert because it receives very little precipitation, mainly in the form of snow. The continent’s cold temperatures result in minimal melting, and the dry, cold air contributes to its classification as the largest desert on Earth.
The largest desert in the world by area is the Antarctic Desert. While the term “desert” often brings to mind images of hot, sandy environments, a desert is technically defined by its low precipitation rather than its temperature or the presence of sand.
Antarctica is classified as a cold desert because it receives very little precipitation, most of which comes in the form of snow. The extreme cold temperatures in Antarctica result in low humidity, which means the air holds very little moisture. As a result, Antarctica has a polar desert climate, making it the largest desert on Earth by area.
So, while Antarctica is not a sandy desert like the Sahara or the Arabian Desert, it is a desert nonetheless due to its deficient precipitation levels. The Antarctic Desert covers an area of approximately 14 million square kilometres (about 5.4 million square miles).
Is the Sahara desert the second largest in the world?
Yes, the Sahara Desert is the largest hot desert in the world. It is located in North Africa and spans across several countries, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan, and Tunisia. The Sahara covers an area of approximately 9.2 million square kilometres (3.6 million square miles), making it more significant than any other hot desert on Earth.
It’s important to note that when people commonly refer to “the desert,” they often mean hot deserts characterized by high temperatures and arid conditions. However, in terms of overall desert size, including hot and cold deserts, the Antarctic Desert (located in Antarctica) is the largest.
The Sahara Desert is the largest in the world, covering over 3.3 million sq. miles, followed by the Arabian Desert, about 2.3 million sq. miles. But if we look at the “desert” design, ” it is defined as “a dry area with very little or no flora and fauna”.
So, by this the largest desert is Antarctica, which is about 5.5 million sq. miles. It is followed by the Arctic, which comprises Alaska, Northern Canada, Greenland, Russia, and others. The Arctic desert is about 5.35 million sq. miles.
Conclusion
The largest desert in the world is the Antarctic Desert. While many associate deserts with hot and sandy environments, a desert is technically defined by its low precipitation levels. The Antarctic Desert encompasses the continent of Antarctica and is the driest and windiest place on Earth.
Antarctica is extremely cold, and much of its precipitation falls in snow. The amount of rainfall in the Antarctic Desert is so low that it meets the criteria for being classified as a desert. Regarding traditional hot deserts, the Sahara Desert in Africa is the largest.
Antarctic Polar Desert, Antarctica is the largest continent, as well as the largest desert in the world. This frigid wasteland dominates the South Pole with a massive surface area of 5.5 million square miles ( 14.2 million square kilometers).
