Atmosphere

Planet Earth atmosphere is bordered by layer of gases and maintained through the Earth’s gravity. Its atmosphere is made up of 77% Nitrogen, 22% Oxygen, 0.97%argon, and 0.038% Carbon dioxide. There is no accurate boundary in the middle of the atmosphere and outer space. It slowly turns out to be thinner and lighter into space. Different planets are made up of different gases and as a result have deep atmospheres.

There are six different atmospheric layers which are: Troposphere, Stratosphere, Mesosphere, Thermosphere, Ionosphere, and Exosphere. The average temperature of atmosphere next to the surface of the earth is 15 degree Celsius. The pressure is calculated on the top of the point where atmospheric pressure is a straight result in the direction of the total weight of the air. Since, when altitude increases the atmospheric density will decrease. This can be calculated through Biometric formula. According to Geologist, The atmosphere is a growing agent essential to the morphology of a planet. Atmospheric circulation takes place because of thermal differences.

According to meteorologist, atmospheric composition decides the climate and its variation. But for a biologist, the atmospheric composition is determined through its appearance of life and evolution. Earth atmosphere guards its organism from ultraviolet rays. The planetary boundary layer is also called as the atmospheric boundary layer. It is the bottom part of atmosphere and its behavior is straight influenced through its contact by the ground.
