Zone of Saturation | Groundwater completely fills all the pores of a material. |
Water table | Upper boundary of the zone of saturation. |
Zone of aeration | Above the water table, moist, but not saturated with water. |
permeability | Tendancy of a material to let water pass through. |
aquifer | Ground water flows throught permable sediments. |
aquiclude | barriers to groundwater flow. |
spring | These natural discharges of groundwater. |

geyser | Explosive hot springs. |
Cave | Underground opening with a connection on Earths surface. |
Sinkhole | A depression in the ground caused by the collapse of a cave or by direct dissolution of limestone. |
Karst topography | Limestone regions that have sinkholes and disappearing streams. |
Stalactite | Hangs from the caves ceiling like icicles and forms gradually. |
stalagmites | Water drips on the floor of a cave. |
Wells | Holes dug or drilled into the ground to reach an aquifer. |
Drawdown | Original water table level and the water level in the pumped well. |
Recharge | Water from precipitation replenishes the water content of an aquifer. |
Artesian well | Recharge is high enough, the pressurized water in the well drilled into an artesian aquifer can spurt above the land surface in the form of a fountain. |
