Earth's atmosphere refers to the different mixed-mixing layers around the Earth:

which hold the earth with its gravity. It is called the atmosphere. This atmosphere absorbs the ultraviolet rays coming from the sun and protects the existence of organisms on earth. Even with heat retention (greenhouse effect), the surface degrades the surface and reduces night temperature compared to day.

The common name given to atmospheric gases for breathing and photosynthesis is the air or air. In the dry air, 78.09% nitrogen in the air, 20.95% oxygen, [1] 0.93% aragon, 20.9% carbon dioxide and slightly There are other quantities of gas. In addition, there is also variable quantity of water vapor, which is approximately 1%. The amount of air and atmospheric pressure are different Ray is varied, terrestrial plants and terrestrial animals to survive in the wind and artificial bayumandalasamuhe trapomandala the world can be found.

The mass of the atmosphere is about 5 × 1018 kg, which is about 11 kilometers (36,000 feet 6.8 miles) on the surface of three quarters. With the increase of the atmosphere the atmosphere stays thin and there is no specific limit between the atmosphere and the space. The Karman line, 100 kilometers (62 miles), or 1.57% of the Earth's radius, is often used as the boundary between the atmosphere and the space. The Earth is 100 kilometers (62 miles) above sea level, or 1.57 percent of the Earth's radius is often used as the boundary between the atmosphere and the space. The atmospheric effects are observed when the spacecraft passes over the line of approximately 120 kilometers (75 miles) in height. Depending on the temperature and the structure, the atmosphere can be divided into several layers .
The study of the Earth's atmosphere and its process is called atmospheric science or aerology. Lion Teesserer de Burt and Richard Assmann are the pioneer pioneers of this science.
