Planet Earth is surrounded by a gaseous layer called the atmosphere.  This wrapping makes the existence of life on our planet possible.

The atmosphere is composed of a series of gases

The Nitrogen (78%) and the oxygen (21%) are principal elements.  Gravity makes it possible for the majority of these gaseous components to stay in the lower zones.
