The Yangtze
From the Tibetan Plateau to the East China Sea
The Yangtze starts on the Tibetan Plateau as the Jinsha, drops off the edge of it, and crosses the whole width of China to reach the sea at Shanghai. That fall is the thing to feel on this plate: high ground in the west, a long descent through the Sichuan basin and the gorges, then the flat, low country in the east. The Jialing, the Wu, the Han and the Gan come in from either side as their own pieces, and the main stem is carved into the surface as a channel.
What a child works out
- A river can start on a plateau five kilometres up and still reach the sea.
- The steepest part of the journey is short; most of the river is slow and low.
- Some of the world's biggest cities sit on this one river system.
