|
|
water cycle |
The continual movement of water among earth's atmosphere, oceans, and land surface through evaporation, condensation and precipitation |
|
|
evaporation |
The process by which water molocules in liquid water escape into the air as water vapor |
|
|
humidity |
the amount of water vapor in a given volume of air |
|
|
relative humidity |
the precentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature |
|
|
psychrometer |
An instrument used to measure relative humidity |
|
|
condensation |
The process by which molocules of water vapor in the air become liquid water |
|
|
dew point |
The temerature at which condensation begins |
|
|
precipitation |
Any form of water that falls from clouds and reaches Earths surface |
|
|
drought |
Long periods of low precipitation |
