artesian well
a well in which water rises above the top of the aquifer without pumping
the icicle-like speleothem that grows down from the roof of a cavern
aerated zone
lies above the water table
a saturated, porous, and permeable layer or stratum

a depression produced in a region where soluble rock has been removed by groundwater
the column-like form that grows upward fromt he floor of a cavern
ice sheet
a very large, thick mass of glacial ice flowing outward in all directions from one or more accumulation centers. the largest example is Antarctica
a deep crack in the brittle surface of a glacier
erosional features produced by valley/alpine glaciers
a depositional feature composed of till and only associated with continental glaciation, not with alpine glaciers
a stream valley, deepened by glacial erosion, that floods as sea level rises
wastage of a glacier that occurs when large pieces of ice breaks off into water. this process occurs where a glacier enters the sea
u-shaped valley
an erosional feature specifically produced by alpine glaciation
a smooth, tapering ridge of till; formed and shaped beneath a continental ice sheet
medial moraine
a ridge of till formed when lateral moraines from two coalescing valley glaciers join
kettle holes
