QuestionAnswer

artesian formation sloping layer of permeable rock sandwiched between two layers of impermeable rock and exposed at the surface
artesian spring natrual flow of water to the earth's surface from an artesian formation
artesian well hole dug through the cap rock of an artesian formation through which water flows freely with no pumping necessary
cap rock top layer of impermeable rock in an artesian formation
capillary fringe region of soil just above the water table that receives moisture from the zone of saturation by capillary action
cone of depression lowered area of a water table produced by pumping water from a well
geyser hot spring that erupts periodically
hard water water that contains relatively large amounts of dissolved minerals
hot spring hot groundwater that rises to the surface before cooling
impermeable rock or sediment through which water cannot flow
karst topography region where the effects of chemical weathering due to groundwater, such as sinkholes and caverns, are clearly visible
mud pot weathered rock around a hot spring that mixes with the hot water to form liquid clay that bubbles at the surface
natural bridge arch of rock formed by groundwater erosion
ordinary spring natural flow of groundwater to the earth's surface
ordinary well hole dug below the water table that fills with groundwater
perched water table secondary water table formed by a layer of impermeable rock above the main water table

sorting uniformity in the size of the particles of a rock or sediment
stalactite cone-shaped calcite deposit suspended from the ceiling of a cavern
stalagmite an upward-pointing, cone-shaped calcite deposit built up from the floor of a cavern
travertine form of calcite that is deposited in terraces around the mouths of hot springs
water table upper surface of the zone of saturation
zone of aeration upper region of groundwater between the water table and the earth's surface
zone of saturation lower region of groundwater where all the pore spaces in a rock or sediment are filled with water
