2 Movement and StorageIf precipitation doesn’t runoff the surface it infiltrates into the ground.Well sorted sediments allow water to infiltrate into the ground more easily than poorly sorted sediments.Porosity- % of pore space.
3 Zone of SaturationZone of saturation- the depth below the Earth’s surface in which ground water fills all the pore spaces.
4 Ground water movementPermeability- the ability of a material to let water through.
6 Groundwater ErosionDissolution- the process of dissolving calcium carbonateCaves- a natural underground opening with a connection to the earth’s surfaceKarst topography- limestone regions that have sinkholes, sinks, and sinking streams.
7 Groundwater ErosionSinkhole- a depression in the ground caused by the collapse of a cave or by direct dissolution below the earth’s surface.
8 Groundwater depositsHard Water- water that contains a high concentrations of calcium, magnesium, or iron.Stalactites- deposits that hang from a cave’s ceilingStalagmites- drip stone deposit that forms below a stalactite.
9 Groundwater systemsSprings- natural discharge of ground water at the earth’s surface
10 Groundwater systemsHot springs- springs that discharge water well above the average air temperature.Geysers- explosive hot springs
11 WellsWell- a hole dug or drilled into the ground to reach a reservoir of ground water
12 WellsArtesian Well- water is forced out of the round because of pressure from the recharge area.
