Mount Everest is growing taller each year and scientists think they’ve finally uncovered the reason why. Reaching the summit of Everest is a feat many mountaineers aspire to achieve but year-on-year that goal gets,

When the Arun River captured a nearby waterway 89,000 years ago, it created a gorge that ultimately resulted in an on-going growth spurt for the world's highest mountain.

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

The culprit is a nearby river eroding and pushing downland, causing the ground under Mt Everest to rebound and lift. “It’s a new additional component of uplift of Mt Everest,” said Matthew Fox, study co-author and geologist at University College London.

Mount Everest is Earth's tallest mountain - towering 5.5 miles (8.85 km) above sea level - and is still growing.

Climbing Mount Everest may be getting even harder as the world's tallest mountain is growing by up to 2mm a year, report scientists at University College London.
