Saltwater intrusion can occur in aquifers near coastlines, when fresh groundwater in the aquifer is displaced by salt water. Coastline aquifers become more vulnerable to saltwater intrusion when freshwater recharge rates are low or withdrawal rates are high. An aquifer in which of the following areas would be most affected by saltwater intrusion?
a small coastal town experiencing a rainy summer
a coastal agricultural area using periodic irrigation
a large inland region of growing cities and farms
a growing coastal city undergoing a drought
Which is Earth's largest source of drinkable water?
lakes
rivers
oceans
aquifers
A regional water board is examining proposals to provide drinking water to a growing metropolitan area. Which of these proposals is most likely to deplete groundwater supplies?
installation of city-owned wells within each neighborhood
construction of a dam to create a large water reservoir
placement of stations along a river to capture and filter water
establishment of a water treatment plant next to a large lake
Subsidence is the collapsing or sinking of land. Subsidence can happen for many reasons. Often it happens when an underground material, such as rock, dissolves and leaves empty space behind. The empty space cannot support the material at the surface. The land above it sinks or collapses. Assuming that the voids underground are forming at the same rate, which of the following would most likely have areas that undergo subsidence?
a pine forest
a field of corn
a large city
a small town
Look at the diagram of a stream with toxic chemicals flowing into it. This diagram models how toxic runoff can pollute a stream and also –
produce acid rain.
cause soil erosion.
create algae blooms.
pollute groundwater.
When rain water reaches Earth’s surface, it can run off into surface water bodies or infiltrate soil and rock to become groundwater. Which of these surfaces would allow the most runoff and least infiltration of rain water?
gravel
cement
sand
grass
The empty spaces in a material are called pores. Porosity is the amount of empty space within a material. Permeability describes how well the pores in a material are connected. Which of these materials would make the most effective aquifer?
a material that has high porosity and high permeability
a material that has high porosity and low permeability
a material that has low porosity and high permeability
a material that has low porosity and low permeability
Which of the following is most responsible for reducing the availability of fresh water in this country?
aquifer depletion
reservoir evaporation
nonpoint source pollution
boat and watercraft emissions
Which of these sources of fresh water corresponds to Source 1?
atmospheric water
surface water
frozen water
groundwater
What percentage of the Earth's freshwater resources is represented by Source 2?
0.3%
30.1%
69.6%
100%
Which source of freshwater is the least abundant according to the graph?
Source 1
Source 2
Source 3
Cannot be determined from the graph
Look at the list of some types of data that can be used to describe a populated area.
1. plants and animals in the area
2. human population density in the area
3. types of roads in the area
4. water table levels in the area
Which types of data must be included in a model comparing risks of groundwater pollution of drinking wells in two different watershed areas?
2 and 4 only
1 and 2 only
2 and 3 only
1 and 3 only
At a city council meeting, a developer outlines plans for a new shopping area. Residents speaking at the meeting voice their concerns that the development will increase runoff and pollute bodies of water in the area. The developer could address their concerns by proposing the addition of which of the following to the plans?
private wells that provide water to each store
sprinklers that hose down parking lots daily
flower gardens that are planted near each store
wetlands that surround the development
Which of the following would happen if precipitation increased within the watershed boundary?
the water table would rise
some tributaries would disappear
hillside infiltration would be reduced
boundaries of the watershed would expand
A group of scientists have decided to study a sedimentary landform deposited by slowly flowing water. The scientists will most likely notice
large pebbles that are continually being moved by traction
a broad, flat surface indicating that the energy in the flow has decreased
gravel that is moving down a steep hill indicating that the energy in the flow has increased
a sharp vertical change in elevation indicating the water’s velocity will increase
Which of the following is NOT a major Virginia watershed system?
Chesapeake Bay
Great Dismal Swamp
Gulf of Mexico
North Carolina Sounds

build a wind turbine.
have fuel trucked in.
have a pipeline built.
build a solar collector.
Which renewable resource would be LEAST affected by increasing global temperatures?

transporting oil over the ocean surface
drilling for oil on the ocean floor
polluting land with oil that reaches the oceans in runoff
polluting air with oil that reaches the ocean in precipitation
Virginia has a large capacity for generating hydroelectric power. Which factor produces the greatest variation in the availability of this renewable energy?
the number of sunny or cloudy days within a typical week
the size of reservoirs used to store water
the distance from the power plant to where the energy is eventually used
the amount of precipitation
