Energy Resources
Test Description: Review for energy resources unit.
Instructions: Answer all questions to get your test result.
1) Why must the voltage be increase before electricity can be transported from the power station to homes?
A
The voltage must be able to move through wet power lines.
B
Most homes use a higher voltage than is produced at the power station.
C
The voltage must be higher to travel long distances because some energy is lost.
D
More voltage is needed to supply business and factories.
2) What is the biggest concern about fracking?
A
The destruction of habitat due to the preparation of the site.
B
The creation of earthquakes
C
The decrease in property values due to the drilling of the well.

A
natural gas
B
coal
C
biomass
D
oil
6) Greenhouse gases are often produced as a result of obtaining and using fossil fuels. Which greenhouse gas most likely has the greatest impact on global warming?
A
carbon monoxide
B
methane
C
carbon dioxide
D
propane
7) The use of which energy resource causes the most damage to the environment?
A
nuclear
B
biomass
C
solar
D
fossil fuels
8) Why is it globally important to conserve trees?
A
Trees help filter the air and return carbon dioxide to the atmosphere.
B
Trees provide a food source for all animals.
C
Trees are a convenient and renewable energy resource but they can be depleated.
D
Trees record the history of environmental climate change.
9) How does coal compare to natural gas?
A
Both are nonrenewable
B
Both are renewable
C
Coal burns cleaner than natural gas
D
Coal is renewable, while natural gas is non-renewable.
10) Which best describes a disadvantage of using wind power to generate electricity?
A
The amount of electrical energy produced from wind power is too great for power lines to withstand.
B
Much of the energy in wind power is lost when it is converted to electricity.
C
The technology used to generate electricity from wind is expensive.
D
The source of wind needed to generate electricity is variable and unpredictable.
11) Which form of energy production would most likely affect migration of spawning salmon?
A
Wind
B
Solar
C
Nuclear
D
Hydroelectric
12) Which statement best explains why coal is used to generate electricity despite the amount of pollution produced by burning coal?
A
Compared to other fuels, coal produces more energy per kilogram.
B
Compared to other fuels, coal is relatively cheap and plentiful.
C
Coal is a renewable source of energy.
D
Coal burns without producing greenhouse gases.
13) If an ash pond from a coal-fired power plant leaks ash into a local creek, which is an environmental consequence?
A
Plants and organisms in the creek may die out.
B
Plants and organisms in the creek may increase.
C
Plants and organisms in the creek will be unaffected.
D
Plant and organisms in the creek will mutate.
14) Which is most likely the greatest impact on the environment when a dam is built for hydroelectric power production?
A
Plant populations suffer from increased competition beyond the dam because more land is available for cultivation.
B
The water cycle is disturbed by the building of a dam because water is concentrated in new areas.
C
Animal populations increase rapidly in ecosystems upstream of the dam because of more available water.
D
The dam destroys habitats by creating reservoirs of water that flood lands upstream of the dam.
15) Acid rain can damage limestone buildings and marble statues. It can also harm organisms living in ponds and other ecosystems. Which pollutant in the atmosphere causes most of the acid rain?
A
nitrous oxide from volcanic eruptions
B
sulfur dioxide from burning fossil fuels
C
soil particles from the use of farm equipment
D
fluorocarbons from aerosol spray cans
16) Which process directly adds carbon into the atmosphere?
A
increasing plant populations
B
forming sedimentary rock
C
decreasing animal populations
D
burning fossil fuels
17) Which will most likely negatively impact the environment when coal is burned for energy?
A
iron
B
nitrogen
C
carbon dioxide
D
water
18) Which of these renewable resources results in an increase in pollution when used to produce energy?
A
geothermal
B
water
C
wind
D
biomass
19) Which of the following correctly identifies how a power plant changes the atmosphere?
A
A plant powered by natural gas releases carbon dioxide.
B
A plant powered by geothermal energy releases nitrogen oxides.
C
A plant powered by geothermal energy releases nitrogen oxides.
D
A plant powered by coal releases oxygen.
20) Which best explains the consequence of burning high-sulfur coal in power plants?
A
Sulfur-containing pollutants are absorbed into the ground, killing the vegetation and causing soil erosion.
B
The release of sulfur-containing pollutants in rivers, lakes, and streams heats up the water, causing thermal pollution.
C
The burning of sulfur-containing coal produces nuclear waste.
D
Sulfur-containing pollutants in the air combine with moisture, producing acid precipitation.
