Earth's atmosphere
Earth's atmosphere consists of 21% nitrogen, 77% oxygen, argon, carbon dioxide and water, and the rest are in a new world is born. There may be a lot of carbon dioxide But it was absorbed into the limestone (carbonate rocks) partially melted to water in the ocean. And be consumed by plants The phenomenon of movement of the earth, and biological processes. Causing the flow of carbon dioxide. The current balance in the atmosphere with carbon dioxide, a small amount. But it is also very important Because it controls the temperature of the earth by the greenhouse. Increase the surface temperature to rise. Without the greenhouse gas carbon dioxide from it. The Earth's surface temperature is too low to make the water in the deep. As a result, the organism can not survive
Earth's atmosphere can be divided into four classes according to temperature changes with altitude above the Earth's surface and about 50% of all matter in the atmosphere in. Class call postcards spheres with a thickness of about 10 kilometers Next up was. Layer stratosphere photosphere. Comprising a layer of ozone that absorbs ultraviolet radiation from the sun's harmful to aquatic life. Floor Mesosphere. It is the object That fell to Earth from space. Is friction with the atmosphere and burn, we see a beautiful meteor. Layer thermoplastic spheres. The outermost layer of the atmosphere Where the temperature increases with height. Space Shuttle Space Shuttle (Space Shuttle) orbiting the Earth at an altitude of 300 km, with temperatures up to 1,000 degrees Celsius, but it can not be burned because of the altitude above the density of the gas. very low
