This activity contains 25 questions.
An aquifer recharge zone is _______.
any area where water infiltrates Earth's surface and reaches an aquifer below
an area where water is released from treatment plants into recharge systems for recovery by the consumers
any area where water fails to infiltrate and winds up as an increased depth of surface water
an area where rivers spread out to enter the ocean
When a water-bearing porous layer of rock, sand, or gravel is trapped between upper and lower layers of less permeable substances, it is _______.
an artesian aquifer
an unconfined aquifer
a recharge pond
The region of a lake where plants are able to attach to the bottom and still reach above the surface is known as the __________.
What is the spatial relationship between the distributions of water and people?
Populations and water resources too often have an inverse relationship (lots of people where there is little water).
People only colonize areas with abundant fresh water.
People are limited to areas with fresh water or saltwater.
Anthropogenic colonization has been limited to shorelines.
The most cost-effective solution for groundwater depletion and land-level subsidence is _______.
allowing no more water to be withdrawn from an aquifer than is naturally recharged
increasing use of desalinization measures
to build more water treatment facilities
What caused the Aral Sea, the fourth largest lake on Earth, to lose four-fifths of its volume in 40 years?
overconsumption for industrial uses
overconsumption by cotton farmers
overconsumption by large resort communities living on its banks
overconsumption by the fishermen and the community living there to support them
Which of the following agricultural irrigation practices is the least useful for conserving water?
"flood and furrow" irrigation
lining irrigation canals to prevent leaks
using low-pressure spray irrigation that sprays water downward toward plants
What is the direct cause of death for the aquatic animals during eutrophication?
toxic secretions by bacteria
a loss of dissolved oxygen in the water
use of all available CO
by the growing algae
drainage of their habitat
A freshwater wetland located in a forested area where the rooted plants are able to grow above the water's surface throughout the entire wetland is called a (an) _______.
The greatest use of fresh water worldwide is _______.
cleaning and watering lawns
drinking and cooking
Salt can be removed from seawater by _______.
absorbing transpired water from plants grown in salt water
mimicking the hydrologic cycle, by taking ocean water and hastening evaporation with heat, and then condensing the vapor
genetic modification of bacteria that remove salt, producing fresh water
processing salt water under low pressure through filters by osmosis
The dams on the Colorado River have NOT provided ______.
more usable water for Mexico
flood control for the southwestern United States
Which of the following wetland environments only occurs for a short period of time each year?

Maria uses no fresh water for these activities.
Maria's water use is consumptive.
Maria's water use leaves no ecological footprint.
Maria's water use in nonconsumptive.
Which of the following would make flooding worse?
restoring a natural wetland
building a grocery store with a large parking lot on an area that used to be a forest
building an airplane
building an artificial wetland on an area that used to contain a factory
A farmer wakes up one morning and sees a large circular area of land on his farm that is sunken. What may be the problem?
The farmer planted too many plants in that area.
The farmer uses water from the local municipality.
The farmer lives too close to the ocean.
The groundwater in the area around the farm has been overpumped.
Which of the following statements about drinking water is true?
Bottled water is better for your health than tap water.
The government does not regulate municipal tap water.
Most bottled water is just purified tap water.
Bottled water is free of all pollutants.
Which of the following is true about desalination?
Desalination facilities do not exist in the United States.
Desalinization facilities are expensive and are primarily found in rich desert nations.
Desalination facilities can be found in every major city in the United States.
Desalination is a process that adds salt to water in order to improve its quality.
What type of irrigation method wastes as little as 10% of the water applied to the plants?
flood and grow irrigation
Which of the following could potentially help to reduce the amount of water used on crops?
using crops not native to arid areas

The United States and Europe have decreased public water use in the past 20 years by __________.
increasing the supply of water
reducing the demand for water with conservation methods
making water more accessible with the help of dams
by removing greater quantities of groundwater
