Geographical question

the atmosphere is a gaseous envelope surrounding the earth and as such it is subject to the gas laws ( approx. 79% nitrogen, 20% oxygen, and 1% trace gases such as argon, krypton, helium, neon, water vapor, and carbon dioxide ) regardless of the layers we have arbitrarily applied. sufficient amounts of these gases have been recorded approx. 600 miles above the equator and minute traces have been detected as far as 1200 miles.

Earth's atmosphere is generally divided into 6 layers with following approx. heights:
1. Troposphere : 16-17.5 kms
2. Stratosphere : 18-22 kms.
3. Ozonosphere : 32-50 kms.
4. Mesosphere : 50-80 kms.
5. Ionosphere : 80-500 kms.
6. Exosphere : Beyond 500 kms.

The legal boundary of territorial airspace is 100km. above sea level. So if you fly 99 km above North Korea they're allowed to shoot you down, but if you fly 111km above them in SpaceShipOne, they're not. Satellites in orbit don't infringe anybody's airspace according to international law. Earth's atmosphere just gets thinner and thinner the further you go out. But if it was all at sea level pressure, it would be a uniformly thick layer 8.75 Km. high.

If I take this question to mean atmosphere which can support human life (without supplementary measures such as oxygen tanks), then about 6km. Humans can climb higher and survive (the summit of Everest is 8.8km), but not for prolonged periods, and at significant risk to health.

Generally considered to be 100 km in height, although there is no fixed boundary. The 100km limit is determined by the lowest altitude at which a satellite can maintain orbit.

The earth's atmosphere has many layers, which do you mean?
