Introduction to importance of atmosphere:
The envelope of the air which surrounds our earth is called “atmosphere”. In fact, we the human beings and other living organisms live at the bottom of an ocean of air. The atmosphere extends to a height of 120 Km. It is present everywhere on the earth. All living beings need air in one form or another form. Atmosphere is divided into four major layers: Troposphere, Stratosphere, Mesosphere and Thermosphere. The composition of the components of air keeps on changing on the account of following reasons:
Atmosphere is a mixture of gases of different densities among which water vapour is one of the lightest gases, followed by nitrogen, oxygen and carbon dioxide.
There is a drop in temperature and pressure with the increase of height.
Importance of Atmosphere:
Atmosphere plays an important role in the formation of clouds, occurrence of rain and formation of snow. It prevents certain harmful radiations from reaching the surface of the earth. It also helps in the formation of winds. The studies on atmosphere also help in making weather forecasts. The weather forecasts help us in taking necessary measures to prevent loss of human life, cattle and crops due to torrential rainfall, cloud brusts, cyclones and dry spells. It also facilitate in taking appropriate measures against droughts and floods. In a way, weather forecasts help us in disaster management.
Importance of Atmosphere:
The envelope of air protects all living beings from the harmful ultraviolet radiations coming from the sun. These rays can cause skin cancer and various health problems, If they reaches our earth. It plays an important role in the formation of winds. Fast moving winds are used for running windmills. The windmills are used for drawing underground water, flour mills and for generating electricity. Winds do help in the movement of sailing ships, gliders etc. Due to presence of atmosphere, transmission of sound is possible. Some musical instruments work only due to presence of atmosphere. The presence of atmosphere enables earth to maintain suitable temperature on the earth for the survival of the living beings.
