Answer:
The earth’s atmosphere, a complex fluid system of gases and suspended particles, did not have its origin in the beginning of the planet. The atmosphere as of today has been derived from the Earth itself by chemical and biochemical reactions. Although the fluid system forms a gaseous envelope around the Earth, its boundaries are not easily defined. They can be arbitrarily defined as the Earth’s atmosphere interface and space interface.
The gases like Nitrogen. Oxygen, Argon, Carbon dioxide and water vapour etc. together make up the total volume of atmosphere. Together with suspended particulates, viz. dust and soot constitute the gaseous turbidity particularly in troposphere. However, the composition of atmosphere and so also the structure is variable in time and space.
The vertical structure of atmosphere is very much related to radiant energy absorption and this can be described in terms of variable of temperature [Fig. 1(A) 2]. Below 60 km. there are two main zones of absorption at the Earth’s surface and in the Ozone layer. The absorbed energy is redistributed by radiation, conduction and convection.
