<h3>What do you mean by high altitude?</h3>
The distance above sea level is known as altitude, just like elevation. If an area extends at least 2,400 meters into the atmosphere, it is frequently referred to as being "high-altitude."
Mount Everest, which is located in the Himalayan mountain range on the border between Nepal and Tibet in China, is the highest point on Earth. 8,850 meters is how high Mount Everest is.
The highest city on Earth is El Alto, which is located in Bolivia. The average elevation of the 1.2 million population is 4,150 meters above sea level.
Air pressure decreases as altitude increases. In other words, low air pressure indicates a high apparent height.
Two things account for this. The primary cause is gravity. Density is the second justification.
