Chapter 9 (7) Group Questions (p. 254-285)
1. Name and describe seven sources of energy. (Three fossil fuels at the beginning of the chapter and the alternative energies are at the end of the chapter.) Also, list a positive and a negative for each. P.257 There are only 6 in the graph, so save room for some more.
2. Name and describe seven parts of a nuclear power plant. (Or draw and label. P. 267)
3. Name and describe the stages of coal formation.
4. Name, describe, and give a use of the three major types of fossil fuels.
5. List the four major areas of energy usage and the % of each. P.257
6. List the sources of electricity and the % of each. P.261
ANSWERS BELOW
1. Name and describe seven sources of energy. Also, list a positive and a negative for each.
Fossil Fuels
1.Petroleum = crude oil=(liquid fossil fuels)
2.Natural Gas = gaseous fossil fuels
3.Coal = solid fossil fuel formed underground from buried, decomposed plant material
Disadvantage-Nonrenewable, produce Carbon Dioxide
Advantage-A lot of energy/gram, readily available.
Alternative Resources
A) Nuclear energy = Energy from the splitting of atoms.
Ad-most energy/gram
Dis-Waste disposal
Fusion=
The process of putting two atoms together.(Occurs on the sun.)
Fission=
The process of breaking atoms apart.
B) Solar =
Energy from the sun
Ad.-Easily accessible.
Dis.-intermittent-Not around all the time.
C) Wind =
Energy from moving air.
Ad.-Easily accessible.
Dis.-intermittent- Not around all the time.
D) Hydroelectric =
Electricity produced by falling water.
Ad.-Inexpensive.
Dis.-Destructive. (intermittent)
E) Biomass =
Organic matter that contains stored energy
Ad.-Renewable.
Dis.-It takes away from food production.
F) Tidal=
Using the tides to produce energy.
Ad.-Renewable.
Dis.-Only in certain areas.
G) Geothermal =
Energy produced by heat within the Earth’s crust.
Ad.-Renewable.
Dis.-Expensive.
2. Name and describe seven parts of a nuclear power plant. (Or draw and label.)
Turbine-Device that is turned by steam.
Generator-Device that changes mechanical energy into electrical energy.
Boiler-Area that converts water to steam.
Condenser-Area that converts steam to water.
Pump-Device that circulates water.
Cooling water-Water that keeps the plant from overheating.
Containment shell-Cement/lead that holds the radiation in.
Fuel rods-The radioactive tube that contains Uranium.
Moderator-Slows down radioactive particles.
Control rod-The other tubes that absorb the radioactive material released during fission.(Determine rate of reaction.)
3.Name and describe the stages of coal formation.
Peat- First stage of coal. This has at least 60 % Carbon.Compression of organic material that squeezes out the materials other than carbon.
Lignite- Second stage of coal. This has at least 70 % Carbon.
Compression of peat that drives off more impurities.
Bituminous- Third stage of coal. This has at least 80 % Carbon. Compression of lignite that drives off more impurities.
Anthracite= Fourth stage of coal. This has at least 90 % Carbon. Compression of bituminous that drives off more impurities.
*They are in reverse alphabetical order!!
4.Name, describe, and give a use of the three major types of fossil fuels.
1.Petroleum = crude oil- liquid fossil fuels
Used to power cars
2.Natural Gas = gaseous fossil fuels
Used to Heat homes
3.Coal = solid fossil fuel
Used to Run power plants
5.List the four major areas of energy usage and the % of each. P.257

Business 16 %
Residential 20 %
Industrial 37 %
Transportation 27 %
6.List the sources of electricity and the % of each. P.261
Coal 51 %
Nuclear Power 20 %
Natural Gas 14 %
Hydroelectric 8 %
Petroleum 4 %
Other 3 %
