The atmosphere is the basis of life on Earth because life is possible on earth due to atmospheric conditions. Due to these atmospheric conditions, the earth is considered to be a unique planet as compared to other planets.
The atmospheric significance found in the context of the Earth and for the existence of life is explained by the following points:
1. The existence of a variety of organisms on the surface of the Earth has only been possible due to the atmosphere.
2. There are many useful gases present in the atmosphere.
3. Gases of the atmosphere are used to make possible various human activities.
4. A component of the atmosphere, the water vapor, plays an important role in determining the climate.
5. Various types of weather phenomena, such as condensation, precipitation, cloud formation, rainfall, frost, snow, dew, hailstone, etc. are the result of atmospheric conditions.
6. Organic dust particles of the atmosphere are most important because they cause many events.
7. The colour of the sky as blue, the appearance of the sky as red in colour during sunrise and sunset, the scattering of the sun’s rays and the reflection of the atmosphere is due to the presence of dust particles.
8. Salt and smoke particles attract water vapor, due to which, the process of condensation takes place.
9. The events visible in the form of fog, mist and haze are also the result of the water vapor and dust particle presence of the atmosphere.
10.The atmosphere protects us by absorbing the ultraviolet rays coming from the sun.
11.Replacement of radio waves is possible due to the layer of ionic particles found in the atmosphere.
All the points mentioned above are the evidence of the fact that the atmosphere and its various layers prove to be the basis of the biological world. If the atmospheric conditions on earth did not exist, then the Earth would also be a deserted planet, just like other planets. From the human perspective, its highest importance is because the direct and indirect influence of atmospheric conditions is the greatest controller of all human activities.
