Explanation:
The Breath of Life: Air
Air is an invisible mixture of several gases, water vapour, and impurities. The mixture of gases includes nitrogen (78%), oxygen (21%), carbon dioxide (0.3%), and other trace gases (0.7%). Among the trace gases, greenhouse gases are most prominent. The air is made up of atoms and molecules. The gas molecules allow the air to move.
The air surrounding the earth is called the atmosphere. The atmosphere is divided into distinct layers- troposphere, stratosphere, mesosphere, thermosphere, exosphere, and ionosphere.
The air is corrosive in nature. The corrosion ability of air depends upon the amount of pollutant present in it. Air in the industrial area contains high levels of sulfur dioxide and nitrogen oxides. The air in the marine environment has traces of chloride salts. The air in rural areas has no harmful pollutants. The air in urban areas contains pollutants from the automobiles and industries.
