| Dew Point | the temperature at which condensation forms from saturated air |
| sleet | rain drops that pass through a layer of freezing air near Earth's surface forming pellets |
| fog | a stratus cloud that forms near the ground |
| humidity | the amount of water vapor in the air |
| wind | air moving in a specific direction (moves from high pressure area to low pressure area) |
| relative humidity | the measurement of the amount of water vapor in the air compared to the amount needed for saturation at a specific temperature |
| weather | a condition of the current state of the atmosphere |
| temperature | a measure of the average amount of motion of molecules |
| clouds | Form when warm air rises, expands and then cools |
| Types of Precipitation | rain, snow, sleet, or hail |
| front | A boundary between two different air masses |
| pressure | Atmospheric ___ is detrmined by the temperature and density of the air and the amount of water vapor in it. |
| precipitation | Storms and ___ occur at fronts. |
| wind direction | Fronts always bring a change in ___ ___. |
| air mass | A lagre body of air with the same properties as Earth's surface under it. |
| isotherm | A line on a weather map connecting points of equal temperature. |
| isobar | A line on a weather map connecting points of equal pressure. |
| percentage | Relative humidy is expressed this way. |
| Dew Point/Air is Saturted | On the sling psychrometer, when both thermometers are at the same temperature and no evaporation takes place this happens. |
| station model | Shows the weather conditions at one specific location |
