In research published in the journal Nature Geoscience, geologists explain the surprising cause of its growth spurt: a rock-eating river.Credit... You might thinkMountEverest, nature’smostimposing skyscraper, would shrink by a few millimeters eachyeardue to erosion or other factors.

Understanding the Context

Instead, it continuesgrowingin height, and science now has a better understanding ofwhy. But the truth is farmoredynamic and surprising. There aremountainsaround the world, such asMountEverestin the Himalayas, that are risingeveryyear. This growth isn’t just a minor technicality; it’s a measurable, ongoing process that scientists have been tracking for decades.

Key Insights

The result of this process is that,everyyear,Everestrises approximately 2 millimeters. In total, during the last 89,000years, it is estimated that it hasgrownbetween 15 and 50 meters attributable to this phenomenon. MountEverestis steadilygrowingtaller at around 4mm peryearwhile the forces of erosion wear away it (Credit: Per-Andre Hoffmann/Alamy). Arching over 8,849 metres (29,032ft) into the sky,Everestis the world’s tallestmountain. But will it always be?

Final Thoughts

“MountEverestand its neighboring peaks aregrowingbecause the isostatic rebound is raising them up faster than erosion is wearing them down,” said Fox. The birth of amountainrange. The story of the Himalaya begins some 200 millionyearsago, as the supercontinent of Pangea began to split into pieces. The Indian plate eventually broke free, trekking northward toward the landmass we now know as Asia.

Recent GPS measurements indicate it is adding up to 2 millimeters annually. Everestformed 40 to 50 millionyearsago when two tectonic plates crashed into each other. The peak would be expected to rise 1 millimeter (.04 inches) peryearthanks to slow-moving shifting still underway, butEverestactually rises twice that amount, reports CNN.
