transpiration
process by which plants loose water from the leaves to the atmosphere
infiltration
downward movement of water throught the soil
precipitation
water that falls as rain, sleet or snow onto surface water or onto land
subsidence
the sinnking of land due to the over pumping of ground water
saltwater intrusion
the water table is lowered and the normal interface between fresh and saline ground water move
inland
overdraft
when more water is removed from an aquifer than can naturally recharge it
less than 1 percent
the percent of earths water not found in oceans glaciers and ice caps
water table
the top zone of saturation whose elevation is influenced by the rate of recharge and removal of
ground water
ground water flow, surface water runoff, evaporation, all of them
which of the following would affect the surface waters on the earth>
agriculture
the greatest use of water globally is for:
aquifers
these are found in deep geologic layers in underground cavern and porous layers of sand,
gravel, and bedrock:
encourage privatization of water utilities
the least likely solution to groundwater depletion
flooding downstream is reduced
all of the following are environmental disadvantages of dams used to produce energy except
colorado river
about 10% of the people in the U.S. depend on the ____ for drinking and irrigation water for
producing electricity
desalination
removing dissolved salts from ocean water or from brackish water in aquifers and lakes is
known as:
depletion of water for agriculture has reduced the sea by almost 90% and increased its
salinity drastically
which of the following summarizes the disaster of the aral sea ( 1 only)

deepening of tube-wells
all of the following means of improving water use effeciency in agriculutre except:
fiber filtration
not associatjed with desalination

for:
southwest
througought the rest of this century the ___ area of the U.S. is predicted to have extended
periods of servere drought
dissolved oxygen concentration
the one measure that can tell the most about the overal quality of a surface water source is:
sediment load
the water feature which would be easure using a secchi disc or other turbidity test
plant nutrients (NO3 and PO43)
the measure which the cause of cultural eutrophication
