Mount Everest's Height Increased by Erosion-Driven Uplift
A new study reveals that river capture and isostatic rebound have caused Mount Everest to rise by up to 150 feet over 89,000 years.
- The Arun River's capture by the Kosi River has intensified erosion, deepening a gorge and causing surrounding mountains to rise.
- This process, known as isostatic rebound, occurs as the Earth's crust adjusts to the removal of material, leading to uplift.
- Mount Everest has grown between 50 to 150 feet over the past 89,000 years, with an annual increase of approximately two millimeters.
- The study utilized computer models and digital elevation data to estimate the impact of river capture on the region's topography.
- These findings highlight the dynamic nature of Earth's surface and the significant role of river systems in shaping mountainous landscapes.
