Which is the Largest and Smallest Plateau in the World?
Plateaus are widespread natural features that can be found on every continent of the world. They can be formed through various geological processes, including volcanic activities, tectonic plates movements, and erosion. In this article, we will explore the largest and smallest plateaus in the world, highlighting their notable features and geographical locations.
Largest Plateau in the World:
The Qinghai-Tibetan Plateau is the highest and largest plateau in the world, covering an area of approximately 2,500,000 square miles (6,475,000 square kilometers). The plateau is situated in central Asia, spanning across northwest China, Tibet, Bhutan, Nepal, Sikkim, and sections of India, Pakistan, and Afghanistan. Averaging an elevation of 16,000 feet (4,877 meters), the plateau makes up about one-quarter of China’s land area, making it the source of several major rivers including the Yangtze and Yellow Rivers.
Geography of the Qinghai-Tibetan Plateau
| Feature | Dimension |
|---|---|
| Length | About 1,300 km (800 miles) in east-west direction |
| Width | About 650 km (400 miles) in north-south direction |
| Elevation | Approximately 16,000 ft (4,877 meters) |
| Area | 2,500,000 sq mi (6,475,000 sq km) |
Smallest Plateau in the world:
The Deosai Plains located in the Skardu Valley of Gilgit-Baltistan, Pakistan, can be considered the smallest plateau in the world. Spread over an area of just 300 square kilometers (116 square miles), these grasslands are nestled among the towering Karakoram mountains at an elevation of 4,500 feet (1,372 meters). The Deosai Plains are home to a variety of flora, fauna, and rare sheep species.
Geography of Deosai Plains
| Feature | Dimension |
|---|---|
| Area | 300 square km (116 square mi) |
| Elevation | 4,500 ft (1,372 meters) |
| Average temperature | 5.6°C (42.1°F) |
| Annual rainfall | 175 mm (6.8 in) |
Regional Plateaus:
Plateaus can be found globally, with notable examples of the largest and smallest regional plateaus:
- Largest Regional Plateau: Africa’s Atlas Mountains
- Smallest Regional Plateau: Australia’s Kimberley Plateau
Interesting Facts About Plateaus:
-
Plateaus can be more fertile than mountains due to their lower elevation and hence less extreme weather conditions.
-
Plateaus are vulnerable to erosion, which occurs due to the gentle angle of the land and periodic weather events.
- Regions with plateaus are subject to varying climate conditions from temperate to tropical with an average temperature ranging between -50°C to -10°C (-58.4°F to 17.6°F).
It is essential to recognize plateaus as unique geological regions that support diverse ecosystems. These regions are vital carbon sinks, and their stability and preservation are crucial to maintain global ecological balance and biodiversity.
In conclusion, the Qinghai-Tibetan Plateau takes the title of the world’s largest plateau, a geological wonder that covers millions of square miles and forms the source of many Asian rivers. On the flip side, the Deosai Plains in Pakistan embody the smallest plateau, nurturing unique flora and fauna with limited resources. Plateaus around the world offer natural beauty, support biodiversity and have a significant impact on regional climates.
