The world’s tallest mountain is getting taller. Mount Everest, also known as Chomolungma, has grown about 15 to 50 meters (50 to 164 feet) higher over the past 89,000 years than expected, according to a modeling study released Monday. The culprit is a ...

According to a new study, a river roughly 46 miles (75 kilometers) from Everest was "captured" by another around 89,000 years ago. The erosion from this event carved away a huge gorge, leading to a loss of landmass that made the mountain experience a major growth spurt.

And, perhaps just as interesting, the answer for Everest’s growth is down at ground level — specifically the Arun River north of the mountain. Thousands of years ago, its course of flow was changed due to erosion, and the Arun connected with its lower reach and became part of the nearby Kosi River system.

Mount Everest is Earth's tallest mountain - towering 5.5 miles (8.85 km) above sea level - and is actually still growing. While it and the rest of the Himalayas are continuing an inexorable uplift that dates back to their birth roughly 50 million years ago when the Indian subcontinent collided with Eurasia,

Researchers say that two rivers merged some 89,000 years ago and gave the mightiest peak in the Himalayas a huge growth spurt.

Mount Everest's increasing height is attributed to the isostatic rebound caused by the merger of the Kosi and Arun rivers about 89,000 years ago. Acco

Scientists may finally have an explanation for why Mount Everest is so much taller than the other great Himalayan peaks – and still growing. Everest is known to be growing by about 2mm a year, and the official figure for its height was last revised upwards by almost a metre in 2020 to 8,848.86m.

The persistent process of erosion is powerful enough to cause the world’s most intimidating mountain range to rise slowly up out of the mantle, growing in elevation

Model suggests a massive uplift partly explains the peak’s impressive height.
