What is the best definition of a water table?
The level to which a river rises when it floods
The boundary between the land and the ocean
The top of the saturated zone in an aquifer
The bottom of the saturated zone in an aquifer
The top of the unsaturated zone in an aquifer
What is infiltration?
The process by which water sinks into the ground
The zone where there are still air spaces left between the particles.
The process by which water vapor turns into liquid water and forms fog or clouds.
The process by which water does not sink into the ground, but rather travels along the surface.
What would cause the water table to lower?
High rates of evaporation and transpiration
Low rates of evaporation and transpiration
Increasing amounts of runoff
A heavy rainstorm with a lot of precipitation
Which soil would have the greatest permeability rate after a rainstorm?
sand (0.02 cm)
silt (0.002 cm)
clay (0.0002 cm)
Which surface would have the most runoff from it after a rainstorm?
Which surface would be impermeable?
A natural, underground area where large quantities of groundwater fill the spaces between rocks is a/an:
ocean
river
aquifer
To use water found in an aquifer people would
build a dam
drill a well to below the water table
purify ocean water
Water collects in an aquifer because the layer below it is
permeable (water can pass through it)
impermeable (water can not pass through it)
transparent
If there is a pollutant in the recharge zone it will likely end up in the
air
fire
groundwater
A place where the water table intersects the ground surface and where a natural flow of groundwater results is called:
a spring.
a geyser.
an aquatard.
a fissure.
Water is able to flow more easily through the aquifer because its material has a ___________.
low permeability
low porosity
high porosity
high permeability
What would happen if we used the ground water faster than the aquifer can refill?
We can just use surface water
They will get the water from the ocean
We can drain them dry
The wells will never dry up
The water table will just get lower underground
In VA, where would a saltwater intrusion happen?
near Richmond area where rocks still have salt in them
high up in the mountains where rivers begin as headwaters
the coast where saltwater trapped within cracks of rocks can be pumped by wells
in the middle of the ocean
