Document Summary
Made up of different layers of air. Temperature reduces with altitude at the rate of -6. 4 degrees celsius. Zone that is categorized by dynamic weather pattern. Categorized by temperature inversion (temperature increases with altitude) High accumulation of greenhouse gases (e. g. nitrogen oxide, methane, mercury) High amount of ice crystals that are formed. Large amount of gamma rays and x-rays. Horizontal motion of air that is caused by differential heating and cooling of the earth"s surface. Pressure can be measured using a mercury thermometer or aneroid barometer. Low pressure systems are caused by warm light air mass. High pressure systems are caused by cold dense air mass. Anemometer is used to measure wind speed. Wind vane is used to measure wind direction. Drives air from areas of more dense air to areas of less dense air, causing winds. Cold dense air mass often sinks to the surface and causes outward movement of air.
