Everest grows more than the rest of the eight-thousanders' thanks to a river that lightens its weight

Mountain erosion by the Arun River causes Mount Everest to rise due to isostatic rebound, differentiating it from neighboring peaks.

Mount Everest is having a growth spurt, say researchers

Mount Everest is currently experiencing a growth in height due to geological processes, adding 15 to 50 meters over the past 89,000 years.

Mount Everest is getting TALLER by the day and has already grown 164ft

Mount Everest is growing by 2mm per year due to river erosion making the mountain lighter, pushing it upwards.

Why Mount Everest Is Growing Taller Every Year

Mount Everest's height is influenced by a historical river merger that increased erosion, allowing the mountain to rise further by up to 165 feet.

How River Piracy' Helped Give Mount Everest a Growth Spurt

Mount Everest's height is partly due to ancient rivers that eroded massive amounts of rock, causing the mountain to rebound upwards by around 50 metres.

Why Mount Everest is the world's tallest mountain

Mount Everest's towering height is due to ancient river activity and geological processes, with significant erosion leading to its elevation increase.
