How high does the atmosphere go?
The outermost layer - the exosphere - extends to approx 10,000 km above the earth's surface.
The Karman Line, 100 km (62 miles) above the surface of the earth, is usually regarded as the boundary between the earth's atmosphere and outer space. The earth's atmosphere has many layers: Magnetosphere - the highest layer Exosphere (500 to 1000 km altitude) Thermosphere (including ionosphere and the Karman Line, 100 km up, which is the boundary between the atmosphere and outer space. Mesosphere Stratosphere (including ozone layer, 15 to 35 km high) Troposphere (including…
That depends how high up you decide to go in the atmosphere. Note that the atmosphere gets thinner and thinner, as you go up. You can multiply the Earth's surface (in square feet) by the height (how high you decide to still consider it part of the atmosphere); that will give you a volume in cubic feet.
