Term
groundwater
Definition
water found underground in prous layers of rocks and soils
Term
aquifer
Definition
underground storage place for groundwater,often stored within permeable rock
Term
surface water
Definition
water flowing or standing on the surface of Earth, such as in lakes or streams
Term
permeability
Definition
ability of rock/soil to have water and other fluids flow through it, has connected pores and cracks that allows groundwater to flow through it
Term
water shed
Definition
a drainage that all water flows into; like a lake, stream, or river
Term
aeration
Definition
when air circulates through water to remove odorous gases and make it look better by bringing the water into contact with the atmosphere
Term
wetlands
Definition
lands that are always wet and control what plants and animals live there
Term
porosity
Definition
a way of measuring pore space in soil and water
Term
permeable
Definition
rock that has connected pores and cracks that allows groundwater to flow through it
Term
recharge zone
Definition
surface area above aquifer where precipatation falls, and eventually percolates down into the porios rock of the aquifer
Term
saline
Definition
salty water; a salty solution
Term
filtration
Definition
fourth step in water treatment; water remaining at the top of the tank after the sediments have settled out is pumped through a filter to remove any unsettled pieces
Term
potable
Definition
fit to drink
Term
non-potable
Definition
not fit to drink
Term
accumulation
Definition
the collect totality of water in the ocean
Term
transpiration
Definition
the passage of water through a plant from the roots through the vascular system to the atosphere
Term
recharge
Definition
the process by which groundwater is absorbed into an aquifer
Term
impermeable
Definition
not allowing the passage of a fluid through intersections
Term
water table
Definition
the highest level in a aquifer where the pores are full of water seperates the zone of saturation from the zone of aeration
Term
percolation
Definition
the movement of water through porous rok and/or soil
Term
artesian well
Definition
a well that's drilled into an aquifer where the ground water is under pressure
Term
artesian spring
Definition
a place where the water table meets the earth
Term
geyser
Definition
a hot spring that erupts periodically shooting hot water and steam into the air
Term
runoff
Definition
water that flows across the Earth's suface
Term
waste water
