HYDROELECTRIC POWER
Ch 18 Map Skills
The United States is the third largest producer of hydroelectric power. Only
Canada and Brazil use more water for hydroelectricity. Together these three
countries make up 37 percent of the world’s hydroelectric power generation. This
map shows how states compare in their use of water for hydroelectric power.
Use the map above to answer the questions below.
1. Using a Key What three states use the most water for hydroelectric energy?
_______________________________________________________________
2. Analyzing Data Do the majority of states use more than or less than 100,000
million gallons of water for hydroelectric power per day?
_______________________________________________________________
3. Making Conclusions How much water per day does the state where you live
use for hydroelectric power?
_______________________________________________________________
4. Making Conclusions Based on what you have learned in this chapter, do you
consider it a good thing or a bad thing if a state uses a high amount of
hydroelectric power?

Which one of the following states has
the most natural coal deposits?
a.
Florida c. Montana
b.
Maine d. Texas
_____
15.
Coal i
s formed when
a.
sediments cover dead marine
organisms and heat converts them
into
complex, energy
rich carbon molecules.
b.
deposits of methane are subjected to
high pressure until they
condense into crystals.
c.
swamplands are buried by sediment.
Then
the added weight creates
heat and pressure, which converts the
plants to coal.
d.
organic remains become trapped in
nonporous rock and merge into
large bodies of complex, energy
rich carbon molecules.
_____
16.
Which of the following is an
advantage of using
fossil fuels for energy?
a.
the resulting air pollution
c.
limited quantities
b.
versatility in its uses
d.
toxic by
products
_____
17.
Which of the following factors does
not
help predict future oil
production?
a.
the number of oil refineries operating
in
the past
b.
changes in technology
c.
costs of obtaining fuels
d.
number of oil deposits discovered
_____
18.
During the process of nuclear fission,
a.
a neutron splits a uranium
235 atom, forming new elements and
releasing several neutrons plus
energy.
b
.
a neutron splits a “daughter” nucleus,
thus creating uranium
234.
c.
radioactivity causes the neutron of a
uranium
235 atom to split in
two.
d.
two lightweight atoms combine to
create a single, heavy atom.
_____
19.
In a nuclear power plant,
a.
three pipe
circuits pump water through the
reactor, turbine, and
cooling tower.
b.
solid uranium pellets are bombarded
with steam in the control rods.
c.
nuclear fusion superheats water in
the reactor, causing steam to
power the turbine.
d.
solid neutron pellets
undergo a chain reaction and release
massive
amounts of heat.
_____
20.
Which of the following is an
advantage of nuclear energy?
a.
It does not produce solid waste.
b.
It is cost
efficient.
c.
It poses no safety risks.
d.
It does not produce air pollution

Cars in developing countries are
often older and
burn gasoline that contains more
sulfur. Cars in
developed countries are generally
newer, have
catalytic converters that reduce air
pollution, and
burn a cleaner gasoline.

of them and their oil leaks are
unregulated.
