The Yazi River terraces in the Kunlun Mountains show how the northern Tibetan Plateau has been gradually rising over time. By dating different terraces, researchers found that the plateau uplifted at a rate of 0.03 mm per year during a period of movement between the Kunlun and Yellow Rivers, around 1.2 to 0.6 million years ago. Since around 387,000 years ago, the uplift rate slowed down to about 0.01 mm per year. This study helps us understand the history of the region's geological changes and how the landscape has evolved over hundreds of thousands of years.
