Chapter 20 Wind: flow of air from one place to another Atmosphere: a layer consisting of a mixture of gasses Weather: the physical conditions of the atmosphere at a given time and location Climate: the average weather conditions during the year Ozone: gas that absorbs harmful ultraviolet radiation from the sun - air consists of 78% nitrogen, 21% oxygen, 1% other gases air pressure: the push that air can exert on its surroundings, and air density therefore increases toward the surface of the earth - with increased elevation comes decreasing air density, gets harder to breathe as you get higher - when air moves from a higher pressure to lower pressure place without adding or subtracting heat= adiabatic cooling - when air moves from a lower pressure to higher pressure place without adding or

Unformatted text preview: subtracting heat= adiabatic heating relative humidity: the ratio between the measured water content and the maximum possible amount of water the air could hold The Atmospheric Layers Troposphere: everything around the surface. can go to -55 degrees C tropopause Stratosphere: gets warmer to about 0 degrees C stratopause Mesosphere: gets to about -85 degrees C mesopause Thermosphere: very little gas, gets warmer cuz its close to the sun Ionosphere: most of the mesosphere and thermosphere. transforms electrons into positive ions Hadley Cells, Ferrel Cells, and Polar Cells. Bottom to top CLOUDS: 1. puffy cotton ball like ones are called CUMULUS 2. thin stable layers are called STRATUS 3. wispy shape and feather like are called CIRRUS...
