What are the topographical features of China?

China's topography is high in the west and low in the east, showing a ladder-like distribution; The terrain is changeable and the mountains are vast. The terrain is high in the west and low in the east, leaning towards the ocean. The topographical features of China are not only high in the west and low in the east, but also obvious three-stage distribution from the western part of the Qinghai-Tibet Plateau to the eastern coastal continental shelf.

The terrain of China is high in the west and low in the east, which is stepped and inclined to the ocean. Mountains, plateaus and hills account for about 67% of the land area, while basins and plains account for about 33% of the land area. The mountains are mostly east-west and northeast-southwest

Millions of years ago, the Qinghai-Tibet Plateau uplifted, which was a major crustal movement in the history of the earth and formed the landform of China. Overlooking the land of China from the air, the terrain is like a ladder, descending gradually from west to east. Influenced by the Indian plate and the Eurasian plate, the Qinghai-Tibet Plateau is rising continuously, with an average elevation of more than 4,000 meters. It is called "the roof of the world" and constitutes the first step of Chinese topography.

From the topographical features, the overall topography of China is distributed in three steps: the first step is Qinghai-Tibet Plateau, the second step includes Junggar Basin, Tarim Basin, Inner Mongolia Plateau, Loess Plateau, Sichuan Basin and Yunnan-Guizhou Plateau, and the third step includes Northeast Plain, North China Plain, Middle and Lower Yangtze River and Southeast Hills.
