Water/Humidity, 6

Humidity Water vapor in the air.
Saturation When the air contains as much water vapor as it possibly can. Warm air can hold more water vapor than cold air.
Relative Humidity A comparison between the amount of water vapor in the air and the amount of water vapor needed to saturate the volume of air.
Condensation The process by which water vapor cools down to become a liquid.
Evaporation The process by which liquid water becomes a gas called water vapor.
Dew a thin layer of tiny drops of water
Water Vapor evaporated water in the air in the form of a gas, you can not see it.
Condensation Nuclei small particles on which water vapor can condense; dust, smoke, tiny salt crystals...
Dew Point the temperature at which the air is fully saturated and dew will form
The Water Cycle (hydrologic cycle) the continuous movement of water between the surface of the earth (lakes, oceans, rivers, dew, puddles...) and the troposphere (layer of gas closest to the Earth's surface).
Transpiration when water vapor is released into the air from leaves of plants
Precipitation Water that falls from the atmosphere in the form of rain, snow, sleet, hail, freezing rain
