A small amount of nitrogen is fixed by lightning, but most of the nitrogen harvested from the atmosphere is removed by nitrogen-fixing bacteria and cyanobacteria (formerly called blue-green algae). The nitrogen cycle transforms diatomic nitrogen gas into ammonium, nitrate, and nitrite compounds.
Gases move from high-pressure areas to low-pressure areas. The bigger the difference between the pressures, the faster the air will move from the high to the low pressure.

This is a strange way of asking a question but "stuff" is made up of things called atoms. EVERYTHING is made up of atoms. In solids, the atoms are tightly compacted together. In liquids, the atoms are sort of close together but move freely. In gasses, the atoms are very spread out. I hope this answers your question, I can't really think of much else to say about this... :D
