Asian topography. On the topographic characteristics of Asia from the perspective of altitude fluctuation and topography

What are the main features of Asian topography?

The first feature of Asian topography is its complexity and changeability, and its topography fluctuates greatly. The Qinghai-Tibet Plateau, with an average elevation of more than 4,000 meters, is known as the "roof of the world". There are the Himalayas, the highest mountain in the world, and Mount Everest, the highest peak in the world at an altitude of 8844 meters. There is a dead sea lowland 392 meters above the Mediterranean sea; There is a Philippine trench 10497 meters deep outside the Philippine Islands. There are mountains and vast plateaus, fertile plains and huge basins; There are many differences, which are complex and diverse. The difference between the peak and the deep ditch is nearly 20,000 meters.

The second feature of Asian topography is that mountains and plateaus are dominant, and plateaus and mountains account for about three quarters of the total area of the whole continent. The average elevation of the Asian continent is about 950 meters, which is the highest continent in the world except Antarctica, and it is covered with thick ice and snow.

The third feature of Asian topography is that it is like a blooming flower, radiating from the middle to all sides, high in the middle and low around.

The Pamirs in the middle of the mainland is like the heart of this flower, and a series of towering mountains extend in all directions from here as the center, as if it were the first petal of this flower. Extending westward from Pamir are mainly Hindu Kush and Suleiman Mountains. Extending eastward from the Pamirs are Kunlun Mountain, Northeast Tianshan Mountain and Southeast Himalaya. There are many plateaus and basins between these huge mountains and their extended mountains, mainly including Qinghai-Tibet Plateau, Mongolia Plateau, Iran Plateau, Tarim Basin, Junggar Basin and Qaidam Basin. In addition, there are Central Siberian Plateau in northern Asia, Arabian Plateau and Deccan Plateau in southern Asia, and Anatolia Plateau in western Asia.

The plains of Asia are like the outer petals of blooming flowers, mostly distributed in the middle and lower reaches of rivers on the edge of the continent. Asia has Mesopotamia Plain in the west, Indus Plain, Ganges Plain and Mekong Plain in the south, West Siberia Plain and Lan Tu Plain in the northwest, Northeast Plain, North China Plain and the middle and lower reaches of the Yangtze River in the east.
