above and separated from main water table by an unsaturated zone
the percentage of rock or sediment that consists of voids or openings
The capacity of a rock to transmit fluid through pores and fractures
body of saturated rock or sediment through which water can move easily
addition of new water to the aquifer (water in)
water leaving the aquifer (water out)
near earth's surface, water will seasonly rise & fall
completely filled with water under pressure, very slowly recharge, no response to seasonal conditions
a place where ground water flows naturally from rock or sediment onto the ground surface. "Some springs discharge where the water table intersects the land surface."
naturally formed underground chambers
closed depression usually resulting from collapse of cave roof
Icicle shaped calcite deposits hanging from cave ceilings
cone - shaped calcite deposits hanging from cave ceilings
large, long-lasting mass of ice, formed on land, moves downhill under it's own weight
occurs in mountainous regions and in the form of valley glaciers.
covers large land masses in earth's polar regions in the form of ice sheets.
Compacted mass of granular snow, transitional between snow and ice
mosaic of interlocking crystals
separates accumulation and ablation zones, marks the highest point at which the glaciers winter snow cover is lost during a melt season
Passive "riding along" of an overlying rigid zone. Fastest at top center slower along margin
upper part where glacier flow happens
ridges of till piled up along the front end of a glacier
thin, extensive layers of blankets of till
annual sediment deposition in glacial lakes
loss of snow
upper part of glacier with perennial snow cover
