Document Summary
Atmosphere is made of different layers of air. Troposphere: temperate release with altitude at a rate of -6. 4 degree celsius, altitude is 0km to 10km, zone that is categorized by dynamic weather patterns, pressure reduces with altitude, temperature reduces with altitude. Tropopause: the transition between troposphere and stratosphere: transition stage, thermal condition becomes frigid or stabilizes. Stratosphere: temperature increased with altitude, high accumulation of greenhouse gases: carbon and nitrogen dioxide, methane, mercury etc. Stratopause: temperature conditions becomes stable: transition stage. Mesosphere: air is exceedingly light, high amount of ice crystals which are formed. Wind is air in motion and is caused by differential heating and cooling of the earth"s surface. Pressure can be measured using mercury barometer or aneroid barometer: greek origin baros: weight. Anemometer is used to measure wind speed km/hr or m/s: greek origin anemos: wind. Wind vane is used to measure wind direction: four major cardinal points: north, west, south, east.
