What Is Altitude?

Elevation refers to the vertical distance of a certain place on the ground above sea level. It is the height difference between a certain place and sea level, and it is usually calculated based on the average sea level. The starting point of the altitude is called elevation zero or level zero, which is the average sea surface of a coastal location. It is based on years of local tide stations to average the position of the sea surface.

Geographical altitude refers to a place on the ground or a geographical thing that is higher or lower than sea level

Affect people

1. The physiological responses brought by altitude are short-term changes, and people will gradually adapt to this high-altitude environment.

2. The impact of atmospheric pressure on people

Highest point

The Mountaineering Team of the People's Republic of China determined that the altitude of Mount Everest recognized by the People's Republic of China in 1975 was 8884.13 meters.

Everest

In 1999, the National Geographic Society used the Global Satellite Positioning System to determine the altitude of Mount Everest to be 8850 meters, but there are many other statements such as 8848 meters, 8840 meters, 8850 meters, and 8882 meters. The most recent survey of Mount Everest was on May 22, 2005. The People's Republic of China re-measured the height of Mount Everest. The mountaineering team successfully ascended the summit of Mount Everest and measured the height of Mount Everest again. It was announced as 8844.43 meters (the peak rock surface elevation measurement accuracy is ± 0.21 meters; the peak ice and snow depth is 3.50 meters).
