What is the highest mountain on Earth?
At 8848 m (29029 ft), Mt Everest is the highest mountain in the world.
Mt Everest is located in the Himalayas mountain range on the border of Nepal and Tibet (China).
In 1865, The Royal Geographical Society gave Mt Everest its English name in honour of George Everest, a Welsh surveyor who was the British Surveyor General of India from 1830 to 1843. The mountain has other names in languages such as Nepali and Tibetan.
The height of Mt Everest was first published in 1856, when it was known as Peak XV.
In 1953 the first successful ascent to the summit of Mt Everest was achieved by New Zealander Edmund Hillary and Nepali sherpa Tenzing Norgay.
There are two main climbing routes and many others that are are less frequently used. Since the first successful ascent in 1953, thousands have climbed to the summit of Mt Everest, hundreds have also died while attempting to do so.
Dangers that await climbers on Mt Everest include high winds, bad weather and altitude sickness.
In recent times the number of climbers attempting to reach the summit of Mt Everest has increased dramatically, causing concerns for both safety and the state of the mountain as climbers routinely leave litter, gear and other debris behind.
There is a South Base Camp located at 5364 m (17598 ft) and a North Base Camp located at 5150 m (16900 ft). Supplies are taken to these base camps and climbers will often stay there while acclimatizing to the high altitude and lower levels of oxygen.
Altitudes above 8000 m (26000 ft) are often referred to as the "Death Zone", a height that humans struggle to survive at for more than a few days.
Plants and animals struggle to survive under the extreme conditions of Mt Everest but birds have been seen at high altitudes and a type of moss grows at heights close to 6500 m (21325 ft).
Although Mt Everest is the highest mountain on Earth above sea level, its summit is only the 5th farthest from the Earth's centre. Because the Earth bulges at the equator, mountains such as Mt Chimborazo in Ecuador have summits that are farther away.
