Groundwater

Groundwater Water located below the Earth’s Surface Two zones Zone of Aeration Zone of Saturation Water table is the boundary where the two zones meet Recharge zone is the ground surface area where water enters the aquifer http://www.groundwater.water.ca.gov/images/recharge.gif

Aquifer http://water.tamu.edu/images/aquifer.jpg

Aquifer A rock layer that stores and allows the flow of groundwater.

Porosity Percentage of open space between individual rock particles Influenced by the size of the particles http://earthnet-geonet.ca/images/glossary/porosity.jpg

Permeability Rocks ability to let water pass through Larger particles produce less friction http://www.mhhe.com/earthsci/geology/mcconnell/images/anim_permeability.gif

Percolation Water passing through the spaces in the soil due to gravitational forces http://www.uvm.edu/giee/AV/EDU/ONLINE/M_Hydro/GIFS/Perc_process.GIF
