What are the parts to the water cycle?
Evaporation Condensation Precipitation Sublimation Transpiration Surface run-off Percolation Groundwater discharge
Watershed:
The region draining into a river.
Significant rivers in the US
Mississippi Missouri Arkansas Tennessee Ohio Rio Granda Sacramento Columbia Susquehanna Connecticut
Evaporation:
Substance changes from a liquid to a gas.
Condensation:
Water vapor turns back into a liquid.
Precipitation:
Water that is to heavy falls as liquid/solid.
Sublimation:
Solid state turns directly to a gas state skipping liquid phase.
Transpiration:
Water released by plants into the air.
Evapotranspiration:
Water turned into gas by evaporation and water vapor released by plants.
Surface run-off:
The water flow which occurs when soil is full to capacity and excess water travels over the land.
Percolation:
The slow movement of water through soil. Cleans and purifies.
Groundwater discharge:
Water that has been underground seeps back into the oceans, or rivers/lakes.
