The earth's atmosphere is composed primarily of nitrogen and oxygen. Nitrogen is 78 percent of the atmosphere, while oxygen is 20 percent of the atmosphere. The remaining two percent is made up of Argon (0.9340%), Carbon dioxide (0.0397%), Neon (0.001818%), Helium (0.000524%), and Methane (0.000179%). The atmosphere also includes water vapor. It is less than 0.25% of the atmosphere as a whole, but may be between one and five percent in any given area.
