An atmosphere is a sheet of gases that surround material body or a planet. It is controlled by the gravity of that body. Argon, oxygen and nitrogen form the three main constitutions of the atmosphere.
Earth’s Atmosphere:
About 80 percent of the mass of earth’s atmosphere is contained below 10 km altitude. The atmosphere of earth is mostly composed of many gases including nitrogen, oxygen, carbon dioxide. This helps protect living organisms from genetic damage by solar ultraviolet radiation, solar wind and cosmic rays.

Atmosphere isa)The layer of nitrogen gases which surrounds the earthb)...
Atmosphere is the layer of various gases which surrounds the earth.
Composition of Atmosphere:
- The atmosphere is composed of various gases such as nitrogen (78%), oxygen (21%), argon (0.93%), carbon dioxide (0.04%) and trace amounts of other gases like neon, helium, methane, and krypton.
- Water vapor is also present in the atmosphere in variable quantities, ranging from less than 1% in cold and dry regions to about 4% in warm and humid regions.
Layers of Atmosphere:
- The atmosphere is divided into five layers based on their temperature and height from the earth's surface.
- The layers are: troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Functions of Atmosphere:
- The atmosphere serves as a protective shield for the earth's surface by absorbing harmful ultraviolet radiation from the sun.
- It also helps in regulating the earth's temperature by trapping heat and preventing it from escaping into space.
- The atmosphere is also responsible for weather patterns and climate changes on earth.
Importance of Atmosphere:
- The presence of a suitable atmosphere is essential for the existence of life on earth.
- The atmosphere also plays a crucial role in providing us with the necessary resources such as oxygen, water, and food.
- Understanding the composition and behavior of the atmosphere is crucial for predicting natural disasters like hurricanes, tornadoes, and tsunamis.
Conclusion:
In conclusion, the atmosphere is a layer of various gases surrounding the earth, which is essential for the existence of life and plays a crucial role in regulating the earth's temperature and weather patterns. Understanding the composition and behavior of the atmosphere is crucial for predicting natural disasters and maintaining the balance of the earth's ecosystem.
