Mount Everest (Tibetian: Chomolungma; Nepali: Sagarmāthā) is the largest and highest mountain on Earth. Mount Everest is in the Himalayas, the highest mountain range in the World. It is about 8,848 metres (29,029 ft) high.
Its peak is on the border of Nepal and China. It is above the Death Zone where the air is too thin for a human being to live, so usually extra oxygen is used when climbing. The Death Zone refers to the parts of Mount Everest that are above 7,600 metres (24,900 ft) above sea level.
Two other mountains also can be named as the "highest" mountains - the Hawaiian volcano Mauna Kea on Hawaii island is the highest mountain measured from the base underwater to the summit (more than 11 kilometres), and the summit of Mount Chimborazo is the fixed point on Earth which is the greatest distance from the center. This is because of the shape of the Earth: the circumference around the Equator is greater than around the poles.
