Rhy 6th Water Cycle
Term | Definition |
---|---|
Hydrologic Cycle | another name for the Water Cycle |
Water Cycle | process by which water circulates between the Earth's oceans, atmosphere, and land |
Water storage, evaporation, transpiration (evapotranspiration), condensation, precipitation, runoff | all the steps involved in the Water Cycle |
Oceans | super storage for the Water Cycle; holds 96.5% of Earth's water and is the primary pathway into the Water Cycle |
Oceans, seas, lakes, and rivers | provide nearly 90% of the moisture in our atmosphere through evaporation |
Evaporation | process by which water changes from a liquid to a gas; primary pathway that water moves from the liquid state back into the water cycle as water vapor |
Sublimation | the process of snow and ice changing into water vapor without first melting into water |
Evapotranspiration | water lost to the atmosphere from the ground surface and transpiration of groundwater by plants through their leaves |
Atmopshere | superhighway used to transport water around the globe; involves condensation and precipitation |
Condensation | process in which water vapor in the air is changed into liquid water; loss of energy allows water molecules to bond; forms clouds and fog |
Precipitation | water released from clouds in the form of rain, freezing rain, sleet, snow, and hail; provides the delivery system of atmospheric water to Earth |
Water Storage | ice, snow, or groundwater locked up in its present state for a relatively long period of time; involves runoff and infilltration |
Runoff | precipitation that did not get absorbed into soil or did not evaporate; ice caps and glaciers provide runoff from melting; water moved by gravity makes its way into places that collect water (rivers, lakes, ponds, oceans) |
Groundwater | large amounts of water stored in the ground |
Aquifer | another name for groundwater; usually describes water-bearing formations |
Infiltration | the downward process of moving water from the land surface into soil or porous rock |
