The Water Cycle
Copy the diagram above onto your worksheet underneath section 1.
Water Cycle Definitions
Condensation - the process by which water vapor in the air is changed into liquid water.
Evaporation - the process by which water changes from a liquid to a gas or vapor.
Precipitation - water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
Percolation - The movement of water through fractures or interstices of a rock or soil.
Transpiration - the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.
Runoff - Flow of water over land surfaces (including paved surfaces), typically from precipitation.
Sublimation - is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage.
Infiltration - Anywhere in the world, a portion of the water that falls as rain and snow infiltrates into the subsurface soil and rock.
