| Question | Answer |
|---|---|
| Process by which precipitation that has fallen on land trickles into the ground and becomes groundwater. | Infiltration |
| The region below Earth's surface in which groundwater completely fills all the pores of a material | Zone of saturation |
| Upper boundary of the zone of saturation | Water table |
| Region above the water table where materials are moist, but pores contain mostly air | Zone of aeration |
| Ability of a material to let water pass through, is high in material with large, wellconnected pores and low in material with few pores or small pores. | Permeability |
| Permeable underground layer through which groundwater flows relatively easily. | Aquifer |
| Impermeable layer that is a barrier to groundwater; such as silt, clay, and shale. | Aquiclude |
| Natural discharge of groundwater | Spring |
| Thermal spring with temperatures higher than that of the human body | Hot spring |
| Explosive hot springs | Geyser |
| A natural underground opening with a connection to Earth's surface. | Cave |
| A depression in the ground caused by the collapse of a cave or by the direct dissolution of limestone by acidic water. | Sinkhole |
| Irregular topography with sinkholes, sinks, and sinking streams caused by groundwater dissolution of limestone. | Karst topography |
| Cylindrical dripstone deposit of calcium carbonate that hangs like an icicle from a cave's ceiling. | Stalactite |
| Mound-shaped dripstone deposit of calcium carbonate that forms on a cave's floor beneath a stalactite. | Stalagmite |
| Deep hole dug into the ground to reach a reservoir of groundwater. | Well |
| Difference between the water level in a pumped well and the original water-table level. | Drawdown |
| Process by which water from precipitation and runoff is added to the zone of saturation. | Recharge |
| Fountain of water that spurts above the land surface when a well taps a deep confined aquifer containing water under pressure. | Artesian well |
