There are five distinct layers of the atmosphere:-

• Troposphere:- It is the densest layer of the atmosphere. It contains the air that we breathe. It also traps terrestrial heat. All changes in the atmosphere, including rain, snow, fog and storm, occur in the atmosphere due to the presence of water vapour.
