Mount Everest has grown by around 15 to 50 metres in the last 89,000 years, and it\u2019s increasing every year. Now, scientists say that\u2019s because the mountain\u2019s water system captured a river.<\/p>\n

When the Arun River joined with another nearby river, the new path created the deep Arun Gorge near Everest<\/strong>.<\/p>\n

<\/div>\n

Now, the river network about 46 miles from the mountain is carving away at the substantial gorge, causing the nearby mountain to rise up by as much as two millimetres a year.<\/p>\n

\u201cMount Everest is a remarkable mountain of myth and legend and it\u2019s still growing,\u201d said PhD student Adam Smith, of UCL Earth Sciences, who co-authored the report.<\/p>\n

\u201cOur research shows that as the nearby river system cuts deeper, the loss of material is causing the mountain to spring further upwards.\u201d<\/p>\n

<\/div>\n

The tallest mountain on Earth, Mount Everest is 8,849 metres high, and rises about 250 metres above the next tallest peak in the Himalayas<\/strong>.<\/p>\n

Today, the Arun River, and the gorge it has created, runs through the mountainous region to the east of Everest and merges downstream with the larger Koshi river system.<\/p>\n

Adventurers heading to Everest\u2019s famous base camp will often cross parts of the Koshi on their route.<\/p>\n

Over millennia, the river Arun has washed away billions of tonnes of earth and sediment along its banks, creating the deep gorge.<\/p>\n

As the huge amount of sediment has been moved away, the land has become lighter and the Earth\u2019s crust has pushed up slowly, leading to Everest\u2019s growth spurt \u2013 it\u2019s a process called isostatic rebound, write the study\u2019s authors.<\/p>\n

The huge amount of upwards pressure under the crust of the Earth in that area now slightly outweighs the downwards force of gravity.<\/p>\n

Everest\u2019s towering height has led to the \u201cinteresting\u201d river system in the area, according to the report\u2019s co-author Dr Jin-Gen Dai at UCL Earth Sciences.<\/p>\n

\u201cThe upstream Arun river flows east at high altitude with a flat valley,\u201d he said.<\/p>\n

\u201cIt then abruptly turns south as the Koshi river, dropping in elevation and becoming steeper.<\/p>\n

\u201cThis unique topography, indicative of an unsteady state, likely relates to Everest\u2019s extreme height.\u201d<\/p>\n

The growth spurt is not unique to Everest, and also affects neighbouring mountains including Lhotse and Makalu, the world\u2019s fourth and fifth highest peaks respectively.<\/p>\n<\/p>\n
