Lecture Notes On ATMOSPHERE, COMPOSITION AND STRUCTURE
by
Asst. Professor, Department of Earth Sciences, Annamalai University

Earth is a unique planet because the life is found only on this planet. The air has a special place among the conditions necessary for life. The air is a mixture of several gases. The air encompasses the earth from all sides. The air surrounding the Earth is called the atmosphere. The atmosphere is an integral part of our Earth. It is connected with the earth due to the gravitational force of the earth. It helps in stopping the ultra violet rays harmful for the life and maintain the suitable temperature necessary for life. 

The air is essential for the survival of all forms of life on the earth. You cannot imagine any kind of life in the absence of it. The atmosphere is like a large protective cover. Besides many gases, water vapour and dust particles are also found in the atmosphere. Due to these all kinds of changes take place in the atmosphere you will study in this lesson. The composition and structure of the atmosphere and the cyclic process of main gases.
