Mount Everest, Earth's highest peak, is growing faster than expected. Recent GPS measurements indicate it is adding up to 2 millimeters annually. This is nearly twice the previously estimated rate. This growth is mainly due to the collision of the Indian and Eurasian tectonic plates over the past 50 million years. However, a new study by the China University of Geosciences suggests that a river capture event may also be helping the growth of the 29,032-foot (8,849-meter) mountain.
