#1. Qinghai Lake

The Qinghai Lake is China’s largest inland lake and its largest salt-water lake. It was created, some 40 million years ago, because of the collision of the Indian and Eurasian plates and the lifting of the Himalayan Sea to create the mountain chain. Being 3,260 meters above sea level, and with a circumference of 360 kilometers, the lake has a water area of 4,340 square kilometers and contains 77.8 billion cubic meters of water.
