Air is the name given to atmosphere used in breathing and photosynthesis. Air supplies us with oxygen which is essential for our bodies. Air contains a variable amount of water vapor‚ on average around 1%‚ while air content and atmospheric pressure varies at different layers‚ air suitable for the survival of terrestrial plants and terrestrial animals is currently only known to be found in Earth’s troposphere and artificial atmospheres. Air is made up of 99% nitrogen‚ oxygen‚ water vapor‚ and inert
