Not sure how high you mean, but if you mean high enough that you need oxygen, you're looking at 20,000 feet. Anything from 10,000 feet upwards (if you are mountain climbing) you still run the risk of altitude sickness as the levels of oxygen are very low, but you can combat this with slow and deep breathing, and don't push yourself too far.
the altitude is high, around 2194m.
At high altitude the temeperature is lower.
High-altitude airflows power both cyclones and anticyclones
jet streams
Clouds at high altitude use the prefix cirro while clouds at middle altitude use the prefix alto. I know this is not in the question but clouds at low altitude don't use any specific prefix. I am also in love with Arturo B.

Altitude Trekking is only used for high mountains like in Himalaya, India. Altitude basically represents the height from the sea level, as u go high, you will trek on more high altitude mountains.
If a person is on pacemaker how will high altitude affect him?
Because of high altitude sickness which is affected by climbing up high were there is high altitude. High altitude is were there is to much oxygen up high, if you breech in to much oxygen you could faint.
Above 100,000 feet altitude (20 miles).
High Altitude Warfare School was created in 1948-12.
The airplane was flying at a very high altitude.
At high altitude the temeperature is lower.
At high altitude the pressure is lower.
These are called 'glaciers', which are disappearing at an alarming rate.
I don't think they can survive high altitude. Because they are so small, and when you are in a high altitude your not close to ground, and the air around you is different. And picturing my Guinea Pig in a high altitude is scary enough because she is so small, and fragile, too, lol. But, the main point is, guinea pigs probably can't survive in a high altitude, only different creatures.
