Water Resources Unit Review

Multiple Choice

Earth’s surface water is found in

• Lakes

• Streams

• Rivers

• All of the above

Multiple Choice

What is the relationship between groundwater and surface water?

• Surface water percolates through the soil to form groundwater.

• Surface water percolates through the soil to form groundwater.

• Groundwater filters through the soil to form surface water.

• Surface water is found in lakes directly above underground water sources.

Multiple Choice

How is fresh water used in industry?

• in manufacturing processes

• in the disposal of waste products

• to generate power

• All of the above

Multiple Choice

Many areas of the world without adequate fresh water have become habitable because

• rainfall patterns have changed.

• water management projects have diverted water to the area.

• icebergs have been towed in to provide fresh water.

• water conservation has been implemented.

Multiple Choice

Which of the following is one way a person could conserve water?

• take a long bath instead of a shower

• wash laundry in small, partial loads

• use a low-flow shower-head and take short showers

• water your lawn daily and at mid-day

Multiple Choice

Which of the following represents nonpoint-source pollution?

• unlined landfill

• polluted wastewater from a chemical plant

• leaking oil tanker

• runoff from agricultural feedlots

Multiple Choice

7. Parasitic worms would be classified as which type of water pollutant?

• Pathogen

• inorganic chemicals

• organic matter

• heavy metals

Multiple Choice

Polluted groundwater is difficult to clean because

• groundwater is deep in the ground and dispersed through large areas of rock.

• pollutants cling to the materials that make up the aquifer and contaminate the clean water.

• the recycling process of groundwater can take hundreds or thousands of years.

• All of the above

Multiple Choice

Most of the pollutants in the ocean come from

• commercial boats and personal watercraft.

• spills from oil tankers

• activities on land.

• leaking underground storage facilities.

Multiple Choice

Most of Earth's fresh water is

• suspended in atmospheric cloud formations

• held in reservoirs behind large dams

• solidified at the North and South poles.

• stored in large underground rock structures

Multiple Choice

The largest watershed in the United States is the

• Mississippi River.

• Yukon River

• Colorado River.

• Rio Grande.

Multiple Choice

When neighborhood residents noticed a large number of dead fish in a local creek, they traced the problem to a nearby gas station. It turned out that a tank of gasoline had developed a leak. This is an example of

• point-source pollution.

• nonpoint-source pollution.

• thermal pollution.

• groundwater pollution.

Multiple Choice

Most large cities get water for households and industries from

• deep wells.

• rivers and lakes

• pumps connected to springs.

• removing salt from sea wate

Multiple Choice

What is an inexpensive solution to providing everyone with more fresh water to use?

• desalination

• drilling more wells into aquifers

• water conservation

• building more dams

Multiple Choice

Which of the following might occur as a result of plastic trash accumulating in the ocean?

• Turtles mistake clear plastic bags for jellyfish, ingest them, and die of intestinal blockage

• Sea birds are strangled by plastic six-pack rings

• Sea mammals, such as seals, become tangled in clear plastic fishing lines and drown

• All of the above

Multiple Choice

Which of the following is most likely to cause conflict between two countries that share a river?

• The “upstream” country drills a large number of new water wells.

• The “upstream” country builds a series of new dams.

• The “downstream” country uses an increasing amount of water for irrigation.

• New industries dump pollutants into the river near the delta where the river empties into the ocean

Multiple Choice

Which of the following is not a true statement about the social and environmental impact of dams?

• Dams are built to resolve disputes between neighboring countries.

• Environmental concern is one reason for their decreased construction.

• Dams allow a river’s natural power to be converted into useful energy.

• Land behind the dam undergoes change because of the change in the flow of the river.

Multiple Choice

An effective approach to preventing future shortages of usable water should focus on

• emphasizing the additive effect of individual attempts to conserve water.

• reducing the pollution of existing water sources by education and enforcement.

• developing and refining new ways to produce fresh water such as desalination.

• All of the above

Multiple Choice

The effects of water pollution on ecosystems

• are always immediate and highly lethal

• result mostly from point-source pollution sources.

• can magnify over time within food chains.

• can be demonstrated by natural eutrophication

Multiple Choice

A common feature of thermal pollution and artificial eutrophication is that they both

• have sources that are difficult to identify and control.

• cause large mats of algae to bloom in fresh water.

• are a result of power plants and other industrial activity

• decrease the amount of oxygen dissolved in water
