A family of five recently replaced its 7-gallon-per-minute showerheads with water-saving 3-gallon-per-minute showerheads. Each member of the family averages 10 minutes in the shower per day. How many fewer gallons of water will the family use each day with the new showerheads?
40 gallons per day
200 gallons per day
1,000 gallons per day
2,100 gallons per day
Why do water sources need to be conserved?
We have an unlimited amount of fresh water.
Pollution reduces the amount of usable water.
Because we need to save it for the whales
What is the relationship between groundwater and surface water?
Surface water is found in lakes directly above underground water sources.
Groundwater filters through the soil to form surface water.
There is no relationship between surface and groundwater; they form independently.
Surface water percolates through the soil to form groundwater.
Many areas of the world without adequate fresh water have become habitable because:
water conservation has been implemented.
icebergs have been towed in to provide fresh water.
water management projects have diverted water to the area.
rainfall patterns have changed.
Most large cities get water for households and industries from:
deep wells.
pumps connected to springs.
rivers and lakes.
removing salt from sea water.
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.
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.
Which of the following is a true statement about the social and environmental impact of dams?
When dams are built along a shared river it can result in 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.
All of the above statements are true.
