a). Coal

b). Wood

c). Oil

d). Natural Gas

b). Wood

Wind and water energy are both indirect forms of 

a). nuclear energy 

b). electrical energy

c). solar energy

d). geothermal energy 

c). solar energy 

Which of the following is not a biomass fuel? 

a). methane 

b). gasohol

c). hydrogen

d). sugar cane waste

c). hydrogen 

The particle used to start a nuclear fission reaction is a 

a). neutron

b). electron 

c). proton

d). atom 

a). neutron 

A part of a nuclear power plant that undergoes a fission reaction is called a 

a). turbine

b). control rod

c). heat exchanger

d). fuel rod

d). fuel rod 

True or False, if false change the underlined word to make the statement true:

The process of burning a fuel for energy is called refinery

False, combustion 

True or False, if false change the underlined word to make the statement true:

Most of the energy used today comes from biomass fuels 

False, fossil fuels 

True or False, if false change the underlined word to make the statement true:

Products made from petroleum are called hydrocarbons

True

True or False, if false change the underlined word to make the statement true:

Geothermal energy is an example of a nonrenewable energy source

False, renewable 

True or False, if false change the underlined word to make the statement true:

Insulation means reducing energy use. 

False, energy conservation 

Describe ways that fossil fuels are obtained. 

Oil is obtained by drilling from oil rigs either on ground or in water. Natural gas is obtained by drilling into the ground and piping out the natural gas. Coal is mined. 

Describe three features of a home that uses solar energy 

1). Solar cells on the roof generate an electric current, a battery stores energy for later use

2). Solar water heat to boil water and create steam

3). large windows act as passive solar energy collectors 

Explain how wind can be used to generate electricty

Wind blows and turns a turbine. The turbine is connected to a generator. When the wind blows, the turbine turns and generates electricity. 

How is a nuclear fission reaction controlled in a nuclear reactor? 

Control rods made of cadmium or boron are inserted between the fuel rods. They absorb neutrons released during fission and slow the speed of the chain reactions. 

How are the three major fossil fuels alike and how are they different? 

They are all nonrenewable sources of energy and need to be combusted to produce energy. They are in different states of matter; oil is a liquid, coal is a solid, natural gas is a gas. 

Describe what kind of nuclear reaction this is and what is happening during the reaction.

This is a nucler fission reaction. After the neutron "bullet" hits the nucleus, the nucleus is split and more nucleus are created from the spare neutrons, which generates more energy. 

Which energy source has the largest change in production from 1973 to today?

Nuclear energy 

Classify the different energy sources from the table according to whether they are renewable or nonrenewable. 

Renewable

Nuclear, hydroelectric 

Nonrenewable

Oil, natural gas, coal 

Write an explanation as to why a house powered by solar energy would be either a good or bad idea. 

Good

Consistent source of energy during the summer months since the summer months have sunlight for a large amount of the 24 hour day 

or 

Bad

There is not enough sun during winter to power a solar house and this is the time when energy is needed the most, not during the summer when temperatures are mild. 

or

Really any explanation that shows your brain functions. 

What is more efficient, an incandescent or fluorscent lightbulb? Why?

A fluroscent lightbulb is more efficient because it uses 1/4th the energy of a incandescent bulb to provide the same amount of light. Therefore, it takes more energy to power an incandescent bulb, making it less efficient than a fluorscent bulb. 

The interior of a car or a window sill with the sun shining on it heats up on a sunny day because of 

a). passive solar heating 

b). solar cells

c). active solar heating

d). indirect solar heating 

a). passive solar heating 

The main function of a dam in producing electriicty is to _________

a). form a reservoir for recreation

b). prevent flooding after a heavy rain 

c). Provide a source of fast moving water

d). provide a source of wind 

c). provide a source of fast moving water

(to turn the turbines which are connected to the generator) 

Geothermal energy is not a widely used source of energy because ____

a). dams can have negative effects on the environment

b). methane gas is produced as a waste product

c). it is difficult to store

d). magma only comes close to Earth's surface in a few locations

d), magma ony comes close to Earth's surface in a few locations 

Which of the following is the first step in producing electricity in a nuclear reactor? 

a). Steam turns the blades of a turbine 

b). Water boils to produce steam

c). U-235 atoms are split by nuclear fusion 

d). Heat is released 

c). U-235 atoms are splut by nuclear fusion 

Why is a nuclear fusion power plant currently not able to be put into use? 

The massive amounts of heat and pressure generated by nuclear fusion current exceed our ability to control a fusion reaction.
