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 process causes liquid water to evaporate from plant leaves and enter the atmosphere as water vapor?
evaporation
infiltration
precipitation
transpiration
condensation
Which surface would have the most runoff from it after a rainstorm?
When people remove vegetation, they ____ runoff and the erosion process.
slow down
speed up
decrease

recharge zone.
Which is one way poor use of fertilizers in agriculture can affect the environment?
It can increase the ability of many species to find suitable habitats.
It can cause pollution of water in lakes and rivers.

Which are the MAIN causes of ocean currents?
winds and differences in ocean water density

glacial melting and precipitation over ocean waters
flooding of rivers and deep ocean thermal events
Which situation will most likely result in flooding after heavy periods of rain?

if freshwater aquifers are porous
if freshwater aquifers are used for drinking water
In the hydrologic cycle, which process contributes to a decrease in groundwater levels?
infiltration
evaporation
precipitation
condensation
To increase their supply of freshwater, a growing community decides to double the number of wells drilled into the local aquifer. Which could be a result of drilling these wells?
an increase in the amount of water flowing into the aquifer
a decrease in the number of rivers flowing in the area
an increase in arsenic pollution in the water
a subsidence of the ground above the aquifer
Which factors are most likely to cause the water table to rise?

Which process most threatens the wetlands of NC?
purifying water in wetlands
regulating fishing in wetlands
removing vegetation in wetlands
tagging of nonnative species in wetlands
Which is one way the changing of tides supports marine life along the North Carolina coast?
by preventing algae blooms in areas close to land
by attracting deepwater marine life to coastal shorelines
by carrying nutrients to filter feeders, such as oysters and scallops
by transporting atmospheric water vapor between the ocean and coastal shoreline
What will MOST LIKELY happen if a warm ocean current travels north or south from the equator?
The current will become warmer, causing it to become more dense and rise.
The current will become cooler, causing it to become less dense and rise.
The current will become cooler, causing it to become more dense and sink.
The current will become warmer, causing it to become less dense and sink.
If people in an area have limited access to freshwater resources, what will MOST LIKELY result?
an increase in the number of aquifers supplying water to the area

Which is one way surface water may become groundwater?
condensation
evaporation
infiltration
runoff
Which result is MOST LIKELY to occur after excessive withdrawal of groundwater in coastal areas?
increased reliance on irrigation because of drier soil conditions
