Unveiling The Biggest desert in the world: Vast & Arid

4 min read

Deserts, often characterised by their lack of precipitation and extreme conditions, cover about one-fifth of the Earth’s surface. These vast, barren landscapes offer more than just sand; they are home to unique ecosystems and a surprising array of life adapted to harsh environments. Below, we explore a top 17 list of biggest desert in the world, delving into their geographical features, climatic conditions, and ecological significance.

Biggest Desert in The World

1. Antarctic Desert 

Covering an area of about 14 million square kilometres, the Antarctic Desert is the largest desert in the world. Despite being covered in ice, it qualifies as a desert because of its extremely low humidity and precipitation. The Antarctic is crucial for regulating the Earth’s climate and its ice cores provide valuable climatic records.

2. Arctic Desert 

Situated in the Arctic Circle, this polar desert spans around 13.9 million square kilometres. It includes parts of Canada, Greenland, Russia, and a few Nordic countries. Like the Antarctic, the Arctic experiences very little precipitation and supports a limited range of biota adapted to cold extremes.

3. Sahara Desert 

Next in our list of biggest desert in the world is Sahara. Extending over 9.2 million square kilometres, the Sahara is the largest hot desert and the third largest desert overall. Located in North Africa, it is renowned for its vast sand dunes, rock formations, and oases. The Sahara’s temperature can reach over 50°C (122°F) and drop considerably at night.

4. Arabian Desert 

The Arabian Desert covers approximately 2.3 million square kilometres in the Arabian Peninsula. It features sandy dunes and rocky plateaus with minimal water sources. Its climate is characterised by extremely dry conditions with only sporadic rainfall.

5. Gobi Desert 

Spanning over 1.3 million square kilometres, the Gobi Desert in northern China and southern Mongolia is known for its harsh beauty and significant historical value as part of the Mongol Empire and the Silk Road. The Gobi is a cold desert, with temperatures that can swing from very hot to below freezing within a day.

6. Kalahari Desert 

Covering parts of Botswana, Namibia, and South Africa, the Kalahari stretches over 900,000 square kilometres. Unlike many other deserts, it supports a relatively rich variety of plants and animals, thanks to periods of transient moisture.

7. Great Victoria Desert 

Australia’s largest desert, the Great Victoria, spans around 800,000 square kilometres. It features sandy and rocky landscapes with sparse vegetation and is known for its unique wildlife, including several endangered species.

8. Patagonian Desert 

Also known as the Monte Desert, it extends across 670,000 square kilometres in Argentina and parts of Chile. It is primarily a cold desert, experiencing more extreme temperature fluctuations than many hotter deserts.

9. Syrian Desert 

Combining elements of a true desert and a steppe, the Syrian Desert covers about 520,000 square kilometres across Syria, Iraq, Jordan, and Saudi Arabia. This arid region is critical for its geopolitical significance and its rich, albeit endangered, biodiversity.

10. Great Basin Desert 

Located in the United States, the Great Basin Desert spans approximately 492,000 square kilometres. It is the largest U.S. desert and features a cold desert climate due to its high altitude. The Great Basin is noted for its unique landscapes, including salt flats, sand dunes, and mountains.

11. Chihuahuan Desert 

The Chihuahuan Desert is the largest in North America, covering around 450,000 square kilometres across Mexico and the United States. It is known for its diverse flora, including numerous cacti species and its wildlife, which includes the Mexican grey wolf and the pronghorn antelope.

12. Sonoran Desert 

Extending across 310,000 square kilometres in the United States and Mexico, the Sonoran is one of the hottest and most biodiverse deserts in the world. It is unique for its summer monsoon season, which brings significant rainfall and supports lush vegetation and a variety of wildlife, including the famous saguaro cactus.

13. Karakum Desert 

Located in Central Asia, predominantly Turkmenistan, the Karakum Desert covers around 350,000 square kilometres. Its name means “Black Sand” in Turkic languages, referring to its dark soil covered by a sparse layer of grass, bushes, and shrubs adapted to its arid climate. The desert is crucial for its role in the economy of Turkmenistan, particularly through the extraction of oil and natural gas. 

14. Colorado Plateau Desert 

The Colorado Plateau in the United States spans across four states—Utah, Colorado, New Mexico, and Arizona—and includes over 337,000 square kilometres. This high desert region features stunning landscapes of deep canyons, towering rock formations, and scattered forests, making it a popular location for tourists and nature enthusiasts. Its climate is characterised by cold winters and hot summers, with precipitation that varies significantly across the region. 

15. Dasht-e Kavir 

Iran’s Dasht-e Kavir, or the Great Salt Desert, is a large desert lying in the middle of the Iranian plateau, covering about 77,000 square kilometres. It features salt marshes, mudflats, and fields of sand and rocks, typical of its harsh desert landscape. The desert is known for its extreme temperatures and the beautiful landscapes.

16. Kyzylkum Desert 

The Kyzylkum, translating to “Red Sand” in Turkic languages, spans Uzbekistan, Kazakhstan, and Turkmenistan, covering an area of about 298,000 square kilometres. This desert is bordered by two rivers, the Amu Darya and the Syr Darya, which provide critical resources for the region’s biodiversity. Kyzylkum is known for its mineral resources.

17. Thar Desert

Also known as the Great Indian Desert, the Thar Desert extends approximately 200,000 square kilometres between India and Pakistan. It really populated and that is why it is included in the list of biggest desert in the world, with a rich culture and history influenced by the unique challenges of desert life.  

Conclusion

Deserts are much more than barren wastelands. Each desert listed here not only occupies a significant area of our planet but also plays a crucial role in Earth’s ecosystems, climate regulation, and biodiversity. The above mentioned list of biggest desert in the world include all the deserts that are diverse in their climatic conditions, landscapes, and ecological roles, highlighting the complex nature of these seemingly inhospitable environments.
