Which is most likely a prevention strategy for flooding?
building artificial levees
reducing water consumption
recycling bottled-water containers
building waste landfills for metals and other contaminants
How could the removal of trees and other vegetation impact an environment?
by increasing oxygen production
by increasing soil formation
by increasing transpiration
by increasing erosion
Which is formed when a section of impermeable rock forces groundwater to move laterally and emerge onto the surface of Earth?
a spring
an aquifer
a geyser
a well
How could a long-term decrease in precipitation impact an area?
It could increase the average water level of lakes in the area.
It could increase the amount of flooding in the area.
It could decrease the amount of possible infiltration in the area.
It could decrease the possible amount of damage to crops in the area.
Which consequence could an exponentially growing human population have on drinkable water?
It could cause a decrease in the amount of waste and pollutants in the water supply.
It could cause an increase in the amount of water available for the
population.
It could cause an increase in cases of waterborne diseases.
It could cause a decrease in needing water for survival.
A local government is considering whether to build a dam. Which is an advantage of building this structure?
It can decrease the accumulation of sediment in the water.
It can improve the natural habitat of plants and animals.
It is an inexpensive process.
It can create a storage place for water.
The drilling for freshwater increases along a coastal area. What is a likely consequence of this action?
an intrusion of salt water into aquifers
the loss of water resources in estuaries
the destruction of estuaries because of an increase in sea levels
a decrease in salt concentration in inlet waterways
What is most responsible for the presence of groundwater in an area?
the movement of water from a confined aquifer into surface water
the movement of surface water and precipitation through soil and rock
the movement of water from streams and rivers to watersheds
the movement of surface water through impermeable rock
Which is the most common contamination source for freshwater resources?
runoff
digging wells
melting of glaciers
lightning
A community decides to upgrade its water purification and management systems. What lasting impact could this have on available freshwater?
It could cause a decrease in water demand.
It could cause a decrease in the water levels.
It could cause an increase in waterborne diseases.
It could cause an increase in the freshwater supply.
A rural, forested area receives a lot of rain in a short amount of time. What would most likely cause potential flooding in the area?
if the area has a large uncharged aquifer beneath it
if the water level in the area is below the zone of saturation
if the ground of the area is already saturated with water
if the ground of the area is mostly sandy soil
Which is the best way to conserve worldwide freshwater resources?
build more roads and highways for cars and trucks
increase the amount of land used to raise cattle
develop more modern coal-powered plants
use more efficient irrigation techniques
In the hydrologic cycle, which process contributes to a decrease in groundwater levels?
infiltration
evaporation
precipitation
condensation
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
a decrease in sanitation and increase in disease in the area
a decrease in weathering and erosion in the area
an increase in biodiversity in 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
dilution of brackish water in estuarine ecosystems
reduced efficiency of local desalination facilities
intrusion of salt water into the water table
What will cause an increase in runoff and infiltration in an area?
contouring farmland
a drought
digging wells
excessive rain
What is a possible consequence of the destruction of a marsh?
decreased flooding
decreased filtering of water
increased types of plant life
increased habitat for organisms
What would MOST LIKELY result if more farms were developed along river basins in North Carolina?
an increase in water pollution
an increase in average rainfall
an increase in nonnative species
an increase in severe weather events
