Language experts believe the word slope came from the Middle English word aslope, an adverb that means “at an angle.” The word has a noun form you can use for something that is at an angle — on a slope — like a steep hill or the ramp in a parking garage.

The flat area on a mountain is known as a plateau.

mountaintop. noun. the area at the top of a mountain.

summit

A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous.

Mountains are tall, rocky features of the landscape. A mountain’s highest point is called its peak, or summit. The bottom of the mountain where it meets normal ground is the base.

The peak of Mount Everest is made up of rock that was once submerged beneath the Tethys Sea, an open waterway that existed between the Indian subcontinent and Asia over 400 million years ago. Possibly as much as twenty thousand feet below the seafloor, the skeletal remains had turned into rock.

Every year, millions of bar-headed geese migrate over the Himalayas and have been doing so for millions of years. They have been seen flying at 28,000 feet. They have flown over Mount Everest!

In the death zone, the human body cannot acclimatize, as it uses oxygen faster than it can be replenished. An extended stay in the zone without supplementary oxygen will result in deterioration of bodily functions, loss of consciousness, and death.

Exact data is unavailable, but government estimates suggest that more than 150 bodies, of the estimated 300 climbers who have died on Mount Everest, remain on the mountain, many deep in snow.

The main reasons for people dying while climbing Mount Everest are injuries and exhaustion. However, there is also a large proportion of climbers who die from altitude related illness, specifically from high altitude cerebral oedema (HACE) and high altitude pulmonary oedema (HAPE).

The risk of dying on the mountain stood at 0.5 percent for women and 1.1 percent for men, down from 1.9 percent and 1.7 percent in 1990-2005, the study said. The number of summit attempts has soared over the decades, leading to four-fold rise in crowding.

4 Answers. Helicopters create lift by their rotor blades pushing an equal mass of air downwards. The air pressure at the top of Mt Everest (29,000ft) is only about 1/3 as much as at sealevel so your helicopter can only generate 1/3 of the lift.

Babu Chiri Sherpa spent 21 hours at the summit without oxygen, even sleeping there. But for lesser mortals the maximum time they should spend there is about 10-15 minutes, AFAIK.

The main reason flight don’t go over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are confusing as the earth itself isn’t flat. As a result the straight routes don’t offer the shortest distance.

Aluminum leads current. Lightning will usually hit a protruding part of the plane, such as the nose or the tip of the wing. The aircraft then flies through the lightning flash, which travels along the body, having chosen the path of least resistance.

When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …

Jet aircraft can safely fly over thunderstorms only if their flight altitude is well above the turbulent cloud tops. The most intense and turbulent storms are often the tallest storms, so en route flights always seek to go around them.

An aircraft accident due to lightning is a rare event despite how many times one plane can be struck. Lightning usually strikes an aircraft on a sharp edge like the wing, nose or antennas. The electricity then flows through the wiring and exits the tail of the plane.
