b) The most abundant is nitrogen.
Earth´s atmosphere contains 78% nitrogen, 21% oxygen, 0.93% argon and 0.04% carbon dioxide and traces of others. Depending of many factors it also contains 3 % water vapour. All these together makes the "air". It protects the Earth from solar radiation (U. V. rays, heat, cosmic rays, etc.).
