Mount Everest lies on the border between Nepal and China.
The mountain is part of the Himalayas, specifically the Mahalangur Himal sub-range. Its summit is on the international boundary between Nepal to the south and the Tibet Autonomous Region of China to the north. Nepal commonly calls it Sagarmatha, while Tibetans call it Chomolungma; Mount Everest is the English name adopted in honor of Welsh surveyor George Everest.
Nepal’s official 2020 measurement gives Everest an elevation of 8,848.86 meters above sea level. The first confirmed ascent was made in 1953 by New Zealand mountaineer Edmund Hillary and Nepali Sherpa Tenzing Norgay. The mountain is often confused with K2, which is the second-highest peak and lies on the Pakistan–China border. Everest’s extreme height results from the collision of the Indian and Eurasian tectonic plates.
