Earth’s Water Supply

2 Groups of Fresh Water1.) Surface (above ground)

2.) Ground (below the ground surface)

Surface Water• Lakes• Ponds• Rivers• Streams/Creeks• Wetlands (marshes, bogs, swamps, sloughs)• Reservoirs

2. Ground Water

• Located beneath the Earth’s surface in spaces between soil and rocks

• Aquifer – underground layer of rock this is saturated with water down to the impermeable rock layer

• Water Table – Top of saturated layer, rises and falls depending on amount of recharge (adding water) and discharge (water removal)

Where is Ground Water Stored?

Water is a Renewable Resource

Terms to Know and Relate:

• Precipitation• Condensation• Evaporation• Transpiration• Sublimation• Surface Runoff• Infiltration• Percolation• Aquifer

• Water storage in atmosphere• Condensation * Evaporation(2) * Spring• *Freshwater Storage • Water storage in oceans• Surface runoff• Snowmelt runoff to streams• Transpiration (2)• Sublimation• Precipitation• Infiltration• Ground water Discharge• Water Storage in Ice and Snow
