Describe ways that fossil fuels are obtained.
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
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
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?
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?
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.
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?
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.
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.
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?
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.

a). passive solar heating
b). solar cells
c). active solar heating
d). indirect solar heating

Why is a nuclear fusion power plant currently not able to be put into use?
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.
Yeako uses up his last chance in Earth Science when he asks a question that has been answered 3 times already. As a result, his ever-patient and totally logical and sane teacher, finally loses any semblance of reality and grabs barbed wire he hid in his desk during a sleep walking incident from nights prior. Dragged by the ankles with the aforementioned barbwire, Yeako is placed next to running snowmobile engine and his hand is brutally twisted and shoved directly onto the engine block. He screams in absolute agony. Why?

Dragged by the ankles with the aforementioned barbwire, Yeako is placed next to running snowmobile engine and his hand is brutally twisted and shoved directly onto the engine block. He screams in absolute agony. Why?
The gasoline snowmobiles use for fuel, which comes from petroleum, a fossil fuel, must be combusted in order to be used for fuel. Since the gasoline must be combusted, high temepratures are a result of combustion engines. The engine is very hot, thus resulting in a burn to Yeako's hand, thereby causing is agonizing scream.
