| | The summit of '''Mount Everest''', or '''Qomolangma''', is the highest point on Earth, at 29,035 ft (8,850 m). (The formerly accepted elevation of 29,028 ft (8,848 m), established in the early 1950s, was recalculated in the late 1990s to be 29,035 ft.) <ref>http://www.mounteverest.net/</ref> | | The summit of '''Mount Everest''', or '''Qomolangma''', is the highest point on Earth, at 29,035 ft (8,850 m).

Climbers must take into consideration the weather conditions, and few climb without supplemental oxygen. | | The climb itself is difficult and a successful attempt requires careful planning.

| − | Typically, the expedition takes several weeks or longer. A base camp is usually established near the bottom of the mountain, then 3 to 4 camps are set up at higher levels. At each camp, climbers spend several days in "acclimatization" to get used to the higher altitude. Climbing at high altitudes can be dangerous and without proper acclimatization can cause serious, life threatening medical conditions. These include High Altitude Pulmonary Edema (HAPE) and High Altitude Cerebral Edema (HACE), which are caused by fluid collecting in the lungs and brain. | + | Typically, the expedition takes several weeks or longer.
