Which is most likely the greatest impact on the environment when a dam is built for hydroelectric power production?
a) The dam destroys habitats by creating reservoirs of water that flood lands upstream of the dam.
b) The water cycle is disturbed by the building of a dam because water is concentrated in new areas.
c) Plant populations suffer from increased competition beyond the dam because more land is available for cultivation.
d) Animal populations increase rapidly in ecosystems upstream of the dam because of more available water.
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) fluorocarbons from aerosol spray cans
b) nitrous oxide from volcanic eruptions
c) sulfur dioxide from burning fossil fuels
d) soil particles from the use of farm equipment
Which process directly adds carbon into the atmosphere?
a) increasing plant populations
b) decreasing animal populations
c) burning fossil fuels
d) forming sedimentary rock
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 will be unaffected.
b) Plants and organisms in the creek may die out.
c) Plants and organisms in the creek may increase.
d) Plant and organisms in the creek will mutate.
How does coal compare to natural gas?
a) Both are renewable
b) Coal is renewable, while natural gas is non-renewable.
c) Both are nonrenewable
d) Coal burns cleaner than natural gas
Which best describes a disadvantage of using wind power to generate electricity?
a) The technology used to generate electricity from wind is expensive.
b) Much of the energy in wind power is lost when it is converted to electricity.
c) The source of wind needed to generate electricity is variable and unpredictable.
d) The amount of electrical energy produced from wind power is too great for power lines to withstand.
Which statement best explains why coal is used to generate electricity despite the amount of pollution produced by burning coal?

Why is it globally important to conserve trees?
a) Trees provide a food source for all animals.
b) Trees are a convenient and renewable energy resource but they can be depleated.
c) Trees record the history of environmental climate change.
d) Trees help filter the air and return carbon dioxide to the atmosphere.

What is the greatest problem with transporting electricity?
a) There is only one main method to creating electricity
b) Some electricity is lost during transmission
c) Electricity is a dangerous power source.
d) Electricity is nonrenewable.
Which major global energy source is used the most as fuel to generate electricity?
a) natural gas
b) oil
c) biomass
d) coal
What is the biggest concern about fracking?
a) The creation of earthquakes
b) The destruction of habitat due to the preparation of the site.
c) The contamination of groundwater due to the toxic chemicals used.
d) The decrease in property values due to the drilling of the well.
Why must the voltage be increase before electricity can be transported from the power station to homes?
a) Most homes use a higher voltage than is produced at the power station.
b) More voltage is needed to supply business and factories.
c) The voltage must be able to move through wet power lines.
d) The voltage must be higher to travel long distances because some energy is lost.
Which will most likely negatively impact the environment when coal is burned for energy?
a) iron
b) water
c) nitrogen
d) carbon dioxide
Which of these renewable resources results in an increase in pollution when used to produce energy?
a) water

Which best explains the consequence of burning high-sulfur coal in power plants?
a) The burning of sulfur-containing coal produces nuclear waste.
b) Sulfur-containing pollutants in the air combine with moisture, producing acid precipitation.
c) Sulfur-containing pollutants are absorbed into the ground, killing the vegetation and causing soil erosion.
d) The release of sulfur-containing pollutants in rivers, lakes, and streams heats up the water, causing thermal pollution.
