6. Kalahari Desert - 360,000 Square Miles
The Kalahari Desert is a vast, semi-arid savanna found in southern Africa. The Kalahari covers a land surface of about 360,000 square miles. It covers parts of Namibia, Botswana, and South Africa. The desert has large areas that are covered with red sand without permanent surface water drainage. It has seasonally inundated pans (dry basins or beds), dry valleys and salt pans. The Okavango is the only permanent river in the Kalahari Desert. It flows to a delta in the northwest of the desert. The Kalahari Desert is home to some vegetation, mostly in the form of desert plants such as certain cactus species and shrubs.
5. Gobi Desert - 500,000 Square Miles
The Gobi Desert covers parts of northwestern and northern China, as well as southern Mongolia. It occupies about 500,000 square miles of total land area. The Gobi Desert is sometimes called the “rain shadow desert,” as the proximity of the desert to the Himalayan Mountains blocks rainfall. The mountains prevent the rain-causing monsoon winds from reaching the Gobi. Most of the Gobi’s surface is not sandy but rather exposed, bare rock. It is a cold desert and occasionally snow accumulates on its dunes.
4. Arabian Desert - 900,000 Square Miles
The Arabian Desert is found in western Asia where it covers most of the Arabian Peninsula. It is the fourth largest desert on earth. It encompasses an area of about 900,000 square miles. It engulfs much of Yemen, the Persian Gulf, Oman, Jordan, and Iraq. Its center, Rub ’al-Khali or the “Empty Quarter,” forms the largest continuous body of sand in the world. The climate of this area is very dry. Temperatures oscillate between regular, characteristically high heat on one end of the spectrum to seasonal nighttime freezes on the other. The annual rainfall is around 100mm on average, but the driest areas receive as little as 30 to 40 mm of rain a year.
3. Sahara Desert - 3,300,000 Square Miles
The Sahara Desert is the third-largest desert in the world, and the world's largest “hot desert.” It occupies a surface area of about 3.3 million square miles. This desert occupies most of the land in North Africa except for the fertile regions of the Maghreb, the Atlas Mountains, and the coastal region adjacent to the Mediterranean Sea. Most of the desert is a barren rocky landscape. The central part of the Sahara is “hyper-arid,” which means that there is no vegetation growing in this area. Most of the rivers in the Sahara Desert are intermittent or seasonal.
2. Arctic Desert - 5,400,000 Square Miles
The Arctic Desert is the second largest desert in the world, covering a land surface of about 5.4 million square miles. The desert partially occupies parts of territories claimed or controlled by Canada, Denmark, Norway, Russia, Sweden, and the United States. As a cold desert, winter temperatures dip to -40 degrees Celsius or below. The desert is characterized by high winds that stir up snow, which creates an illusion of persistent and continuous snowfall. The Arctic is very vulnerable to climate change. In recent years, alarms have been raised over the reduction in the amount of sea ice in the area. The shrinking of the Arctic Desert is especially concerning as it could have a serious impact on global water levels.
1. Antarctic Desert - 5,500,000 Square Miles
Antarctica is the largest desert in the world. Located around the South Pole, it is the driest, windiest, and coldest continent on earth. It also has the highest average elevation on earth compared to any other continent. The entirety of Antarctica is a desert - the continent receives less than 200mm of precipitation every year. Temperatures in Antarctica are generally very cold and may drop as low as -89 degree Celsius in winter. Partially due to these extremes temperatures and a lack of water, there are no permanent residents in Antarctica. Temporary residents number from 1,000 to 5,000 depending on the time of year. These groups consist mainly of scientific researchers and their supporting personnel. The Antarctic Desert covers a total area of about 5.5 million square miles. Due to the glare of the sun off of the ice, sunburn and vision problems are a concern to people in Antarctica.
