The Earth’s atmosphere is a layer of gases surrounding the planet Earth that is retained by the Earth’s gravity. It contains roughly (by molar content/volume) 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, trace amounts of other gases, and a variable amount (average around 1%) of water vapor. This mixture of gases is commonly known as air. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night.

Atmospheric gases scatter blue light more than other wavelengths, giving the Earth a blue halo when seen from space.
Nitrogen 78.0842%
Oxygen 20.9463%
Argon 0.93422%
Carbon dioxide 0.0384%
Water vapor about 1%
Other 0.002%

Layers of the atmosphere

(not to scale)

There is no definite boundary between the atmosphere and outer space. It slowly becomes thinner and fades into space. Three quarters of the atmosphere’s mass is within 11 km of the planetary surface. An altitude of 120 km marks the boundary where atmospheric effects become noticeable during re-entry. The Kármán line, at 100 km, is also frequently regarded as the boundary between atmosphere and outer space.
