A new study reveals Mount Everest is growing faster than expected, attributed to the Kosi and Arun Rivers' merger 89,000 years ago. Isostatic rebound contributes about 10% to Everest's annual uplift rate.

The early Everest expeditions had a hard time. As they froze in inadequate clothing, went hungry on indigestible pemmican diets, and bet their lives on frail hemp ropes, perhaps they might have taken some solace in knowing that,

Scientists explain what gave Everest its height advantage over its neighbors and contributes to making it grow taller (by millimeters) every year.

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 nearby river eroding and pushing down land, causing the ground under Mount Everest to rebound and lift.

Scientists say Mount Everest, the world’s tallest peak, is still growing thanks in part to the merger of two river systems tens of thousands of years ago.

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.

Mount Everest, the tallest mountain in the world, continues to grow every year due to an unusual river formation at its base that affects it and other nearby peaks

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,

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.

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.
