Porosity and Permeability and Groundwater
Size
A factor that determines porosity. The substance may be large or small
Shape
A factor that determines porosity. The substance may be rounded or angular
Sorted
A factor that determines porosity. The substance may be sorted well, poorly, or unsorted
Clay
A sediment that is impermeable
Sand
A sediment with high porosity
Stalactites
Cave formations which are formed on the ceiling of a cave
Stalagmites
Cave formations which are formed on the floor of a cave
Aquifer
Layer of rock or sediment that allows groundwater to pass freely. It can trap water between permeable and impermeable layers, called aquicludes, sometimes
Glaciers
Most natural fresh water on Earth comes from this source
Gaining
Pond or stream- water is discharged to surface waters from ground water at the point where the water table intersects the surface of the land
Permeability
The ability of water to flow easily through a rock or sediment
Porosity
The percentage of open spaces in a rock or sediment
Infiltration
The seepeage of water into the earth
Column
This is formed when a stalactite and stalagmite join
Aeration
This zone is above the water table- the ground is filled with water and air between rock pore spaces here
Saturation
This zone is the underground area which is saturated with water
Cone of Depression
Too much water is being used and causes water table to drop and ground around well dips down
Well
Used to pull water from water table- pumped by machines
Impermeable
Water cannot pass through a substance said to be___
Artesian Well
Water is under pressure and flows out without pumping
Water Table
ground below is saturated with water and water settles here
