| Question | Answer |
|---|---|
| Layers of the atmosphere | troposphere,stratosphere,mesosphere,thermoshpe-re,exosphere |
| things found in each layer | |
| ozone | protects us from harmful ultraviolet radiation. |
| temp changes in layers | |
| conduction | transfer of energy that occurs when molecules collide. |
| convection | transfer of energy by the flow of a heated substance. |
| radiation | transfer of heat through space by visible light, ultraviolet, IR radiation, and other forms of electromagnetic energy. |
| advection | sending energy back into space. |
| heat | the transfer of energy that occurs because of a difference in temperature between substances. |
| temp/pressure/density | measurement of how rapidly or slowly molecules move around. |
| condensation | |
| evaporation | |
| phase change | |
| sublimation | |
| dew point | temperature to which air must be cooled, at constant pressure, to reach saturation |
| precipitation | includes all forms of water, liquid, solid that fall from clouds |
| groundwater | |
| aquifer | |
| rain+drizzle | liquid water that falls from clouds to earth. coalescence- water droplets collide + get bigger |
| snow | precipitation that hits the ground as solid ice crystals |
| sleet | freezing rain must hit ground in frozen state |
| hail | very large ice pellets that hit the ground |
| acid rain+ effects | forms when rain uses nitrates + sulfates as condensation nuclei. |
| glaze | ice formed when rain hits freezing surface + then freezes |
| clouds | |
| height prefixs | cirro- high clouds with bases starting at 6000m. alto-alto middle clouds with bases between 2000 and 6000 meters strato- low clouds below 2000 meters |
| shapes | cirrus- Latin meaning hair, horse tails wispy , stringy clouds made of ice.- cumulus-Latin meaning pile or heap puffy lumpy looking fair weather clouds-stratus-layers flat featureless sheets of clouds-nimbo-cloud or rain low gray rain clouds |
| ingredients of clouds | water vapor, condensation nuclei, ice, dust, salt, dirt, ash, smoke, soot, smog, nitrates and sulfates |
| pressure | weight of the atmosphere per unit area |
| barometer | instruments used to measure air pressure |
| relationship to humidity and temperature | |
| pressure hot + cold air | |
| hwo wind flows into lows + out of highs | |
| units | inches, millibars and centimeters |
| pressure gradients | when lines are close together it is a steep pressure gradient |
| isobars | |
| sling psychrometer | |
| def of meteorology | |
