New research reveals Mount Everest's growth linked to river erosion and tectonic activity

Mount Everest is growing at an increased rate of about 2mm per year, according to new research. Scientists suggest that the Arun River, which changed course 90,000 years ago, may have eroded rock that weighed down the mountain, allowing it to rise by 15 to 50 meters. The study highlights that while the river's influence is notable, the primary reason for Everest's height is the tectonic activity from the collision of the Indian and Eurasian plates. This ongoing tectonic process, marked by frequent earthquakes, plays a crucial role in shaping the mountain's elevation. Everest's unique position along a megathrust fault allows it to grow more consistently than other peaks. The fault beneath Everest experiences regular ruptures, contributing to its height, while other areas of the fault remain inactive for longer periods.
