Air is primarily made up of two elements, nitrogen and oxygen. Nitrogen makes up 78.05% of air and oxygen another 20.95%. The remaining less than 1% is primarily argon, but carbon dioxide, neon, helium, methane and krypton are also present in air. Air also contains suspended dust, spores, and bacteria, as well as water. The amount of air varies tremendously with location, temperature, and time. In deserts and at low temperatures, the content of water can be less that 0.1% by volume. In warm, humid zones the air may contain over 6% water.
