Saltwater intrusion can occur in aquifers near coastlines, when freshwater is displaced by saltwater. Aquifers are more vulnerable to saltwater intrusion when recharge rates are low or withdrawal rates are high. In which location would saltwater intrusion be a problem?
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. It happens when underground material dissolves and leaves empty spaces. The empty space cannot support the surface material and the land above collapses or sinks. Which of the following would MOST likely have areas undergoing subsidence?
a pine forest
a field of corn
a large city
a small town

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 & rock to become groundwater. Which of these structures would allow the MOST runoff and LEAST infiltration of rain water?
gravel
cement
sand
grass
Which of these materials would make the MOST effective aquifer?
a material with high porosity and high permeability
a material with high porosity and low permeability
a material with low porosity and high permeability
a material with 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

How could a shopping center developer address the concerns of increased runoff and pollution in an area?
Add private wells that provide water to each store
Add sprinklers that hose down parking lots daily
Add flower gardens that are planted near each store
Add 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
The engineering team that is designing a scientific research station on the Arctic permafrost has to provide the station with energy for cooking, heating, and lighting. Considering the fragile environment and other conditions, the BEST choice is probably to...
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?
hydropower
wind energy
geothermal power
biomass energy
Just under 1/2 of the oil that enters the ocean water comes from natural oil seeps on the ocean floor. The other 1/2 comes from human activities. Which human activity contributes the MOST oil to the oceans?
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
Four types of fuel-efficient vehicle engines currently in use are listed below. Which type contributes the LEAST to air pollution at point of use?
biodiesel
gasoline
electric hybrid
hydrogen cell
Irrigation of crops can lead to a drop in the water table, as groundwater is removed from an aquifer. Conservation officials can limit irrigation in order to allow an aquifer to recharge with water. Which Area listed would need to limit the amount of irrigation used?
Area 1
Area 2
Area 3
Area 4
Virginia has major rock and mineral resources. Which resource is commonly used for road and building construction?
silica
crushed stone
limestone
zirconium
Based on this graph, what has been the overall trend in coal production?
It has increased
It has decreased
It has remained constant
A student read that the amount of fossil fuels that are available will eventually decline, leading to a short supply of fuel for cars. What is the MOST likely effect of a fossil fuel shortage?
More people would use airplanes for travel
The fossil fuels would be manufactured in factories
There would be more research on the use of alternative fuels
The technology will be focused on cars that do not use energy
Chlorofluorocarbons (CFC's) have been banned since 1996 because they damage the ozone. Based on the graph, which summary best explains the effect of the banning of CFC's?
The ozone hole has grown some & the negative effects on the atmosphere have stalled
The ozone hole has completely grown back & the threat from CFC's has been completely eliminated
From 1990 to 2010, the ozone hole area is constantly decreasing
The ozone hole area continues to grow at a steady rate
