The atmosphere is a layer of gases surrounding a planet, including Earth, the planet's surface until far in outer space. On earth, the atmosphere contained from 0 km altitude above ground level, up to about 560 km from the earth's surface. The atmosphere is composed of several layers, named after the phenomenon that occurs in the layer. Transitions between the layers to one another takes place gradually. The study of the atmosphere at first made to solve the weather problems, the phenomenon of refraction of the sun at sunrise and sinks, and flashing star kelipnya. With sensitive equipment mounted on the vehicle outer space, we can gain a better understanding of the following atmospheric phenomena that occur in it.Earth's atmosphere consists of nitrogen (78.17%) and oxygen (20.97%), with a little argon (0.9%), carbon dioxide (variable, but approximately 0.0357%), water vapor and other gases. The atmosphere protects life on Earth by absorbing ultraviolet radiation from the sun and reducing temperature extremes between day and night.75% of the atmosphere is in 11 km from the planet's surface.The atmosphere has no abrupt boundary, but rather thinned gradually by increasing altitude, there is no definite boundary between the atmosphere and outer space.TroposphereThis layer is at the lowest level, the ideal gas mixture to sustain life on earth. In this layer protected the life of the shock radiation emitted by celestial objects other.Compared with other atmospheric layer, this layer is the thinnest (approximately 15 kilometers from ground level). In this layer, almost all types of weather, sudden temperature changes, wind, pressure and humidity that we experience daily progress.The lowest elevation is the warmest part of the troposphere, because the Earth's surface absorbs heat radiation from the sun and distribute the heat into the air.Usually, if the altitude increases, air temperature will decrease steadily (steady), from about 17 ℃ to -52 ℃. In particular the earth's surface, such as mountainous areas and highlands can cause anomalies on the temperature gradient.Between the stratosphere and troposphere there is a layer called layer Tropopouse.StratosphericGradual shift from the troposphere to the stratosphere starts from a height of about 11 km. Temperatures in the stratosphere of the most under relatively stable and very cold - 70oF or about - 57oC. In this layer of very strong winds occur with a certain flow pattern. High clouds type cirrus sometimes occur at the bottom, but no significant weather patterns that occur in this layer.From the middle of the stratosphere and above, the pattern of temperature change becomes increasingly growing up, due to increased concentrations of ozone layer is increased. This ozone layer absorbs ultra-violet radiation. The temperature in this layer can reach about 18oC at an altitude of about 40 km. Stratopause separates the stratosphere layer with the next layer.MesosphereApproximately 25 miles or 40km above the earth's surface there is a transition layer to layer mesosphere. In this layer, the temperature again falls as altitude increases, up to about - 143oC near the top of this layer, ie less than 81 km above the Earth's surface. This allows the temperature as low as noctilucent clouds occur, which are formed of ice crystals.ThermosphereTransition from the mesosphere to the thermosphere begins at an altitude of about 81 km. Named after the thermosphere due to the rise in temperature is quite high at this layer is about 1982oC. This change occurs because the absorption of ultra violet radiation. This radiation causes chemical reactions to form electrically charged layer known as the ionosphere, which can reflect radio waves. Before the advent of the satellite era, this layer is useful to help emit radio waves over long distances.Aurora phenomenon also known as the northern lights or southern lights happen here.ExosphereThe existence of the reflection of sunlight reflected by meteoritic dust particles. The reflected sunlight is also referred to as light ZodiakalThe composition of the Earth's atmosphere
