高一必修一地理知识总结(国外英文资料) Unit 2 atmosphere One: composition and vertical stratification of the atmosphere 1) the composition of the lower atmosphere: dry clean air (nitrogen - the elementary element of the organism, oxygen - biological material basis to maintain life activities, the basic materials of carbon dioxide - photosynthesis, ozone - absorbs the suns ultraviolet umbrella of earth life), water vapor and solid impurity (necessary conditions of cloud to rain) 2) : vertical stratification of the atmosphere (text 29, figure 2.1) The effect of high temperature atmosphere motion on human activities The upper atmosphere 2000-300km of ionosphere reflects radio waves The stratosphere, 50 to 55 kilometers, increases with height and the ozone absorbs ultraviolet radiation. Its good for high-flying In low troposphere weft: 17-18 km, weft: 10-12 km and high latitude: 8-9 km With height increases with the decreasing convective weather phenomenon is complicated, the most closely relationship with humans Two: atmospheric heat effect (1) the effect on solar radiation Absorption: selectively, water vapor and carbon dioxide absorb infrared, ozone absorbs ultraviolet light, and absorbs less in visible light Reflection: no selectivity, the thicker the cloud, the stronger the reflection, during the summer cloudy day, the temperature is not very high Scattering: selectively, the light that is shorter in wavelength is easily scattered, so the clear sky is blue (2) the insulation effect on the ground (1) atmospheric absorption surface long-wave radiation, intercept heat and warming, because the atmosphere for the absorption of solar shortwave radiation ability is bad, but for the ground long-wave radiation absorption effect is strong, so the ground most of the radiation is absorbed by the atmosphere It is a kind of atmospheric radiation which is directed towards the ground and compensates for the heat of the ground Two: the atmospheric heat condition The heat of the atmosphere 1) heat cir
