#  Mount Everest: the highest mountain in the world





Almost everyone calls Mount Everest "the highest mountain in the world," and climbers from everywhere travel to Everest hoping to earn the distinction of climbing the "World's Highest."


Mount Everest is called the world's highest mountain because it has the "highest elevation above sea level."We could also say that it has the "highest altitude."



The peak of Mount Everest is 8,850 meters (29,035 feet) above sea level. No other mountain on Earth has a higher altitude. However, some mountains might be considered "taller" (with taller being "the total vertical distance between their base and their summit")







In 1865,  Mount   Everest was given its official name by the Royal Geographical Society, upon a recommendation by Andrew Waugh, the British Surveyor General of India. As there appeared to be several different local names, Waugh chose to name the mountain after his predecessor in the post, Sir George Everest, despite George Everest's objections.

There is very little native flora or fauna on Everest. There is a moss that grows at 6,480 metres (21,260 ft) on Mount Everest. It may be the highest altitude plant species. An alpine cushion plant called Arenaria is known to grow below 5,500 metres (18,000 ft) in the region
. It lurks in crevices and may feed on frozen insects that have been blown there by the wind. There is a high likelihood of microscopic life at even higher altitudes.

Mount Everest attracts many climbers, some of them highly experienced mountaineers. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the "standard route") and the other from the north in Tibet. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, and wind, as well as significant hazards from avalanches and the Khumbu Icefall. As of 2016 there are well over 200 corpses on the mountain, some of which serve as landmarks.[

The first seven attempts on Everest, starting with a reconnaissance in 1921, approached the mountain from Tibet, where a route to the summit via the North Col and North Ridge seemed possible. All were unsuccessful. George Mallory, who spearheaded the first three expeditions, lost his life with Andrew Irvine during a failed ascent in 1924.

Overall, more than 600 climbers from 20 countries have climbed to the summit by various routes from both north and south. Climbers' ages have ranged from nineteen years to sixty. At least 100 people have perished, most commonly by avalanches, falls in crevasses, cold, or the effects of thin air.

Climbing on Everest is strictly regulated by both the Nepalese and Chinese governments. Permits cost thousands of U.S. dollars ($50,000 for a seven member party in 1996), and are difficult to obtain, and waiting lists extend for years. Treks to Everest base camp, minus the summit attempt, are becoming increasingly popular on both the north and south sides of the mountain. On the north side, a Buddhist monastery stands at the foot of the Rongbuk Glacier, beneath Everest's spectacular north face. The monastery is one of two whose locations were selected specifically to allow religious contemplation of the great peak. The other is the Thyangboche Monastery in Nepal. The once-active Rongbuk monastery in Tibet has required much rejuvenation from the destruction it experienced following China's invasion of Tibet.

Two Men Climbed It 21 Times



Two Sherpas, Apa Sherpa and Phurba Tashi, hold the joint record for most Everest ascents. The pair have each managed to reach the summit an impressive 21 times. Phurba reached the top of the world three times in 2007 alone, and Apa has successfully summited the mountain almost every year between 1990 and 2011.
Apa says that he has seen clear changes on Everest caused by global warming over the years. He has spoken of his concerns over melting snow and glaciers, which expose the rock and make it increasingly tough to climb. He also worries for the well-being of Sherpas, after losing his own home in a flood caused by the melted glaciers. Apa has dedicated several Everest ascents to raising awareness of climate change.
