Nuclear Wastes
100
Define acid rain
rain that is more acidic than normal water
100
What is the first step in water purification
Sedimentation
100
Define renewable and nonrenewable resources
Renewable resources can be replaced Nonrenewable resources cannot be replaced once they are used up.
100
Contrast fission and fusion in relation to nuclear energy
In fission large atoms break apart into smaller atoms in fusion small atoms merge to form larger atoms
100
What are the two main types of waste produced from nuclear power plants
thermal and radioactive
200
Describe the major cause of acid rain
Burning fossil fuels
200
What is the second step of the water purification process
Coagulation
200
Name two renewable resource and Two nonrenewable resource
Renewable: Water, trees, Wind, Sunlight Nonrenewable: Oil, Gas, Coal, Iron, Gold
200
Define nuclear energy
Energy that is stored in the nucleus of an atom
200
Describe one way that nuclear wastes can be disposed of
they can be buried, recycled and used again, stored in underground storage sites
300
What are the main chemicals in air pollution that create acid rain
Sulfur Dioxide and nitrogen oxide
300
Compare sedimentation and coagulation
Sedimentation causes the heaviest particles to sink first. Coagulation uses chemicals to make the particles stick together and become heavier so they sink
300
Explain how an aluminum soda can be both a renewable and a nonrenewable resource
Aluminum is nonrenewable but soda cans can be recycled
300
What is the fuel used in nuclear reactors
Uranium
300
Describe the effects of thermal pollution to areas around the power plant
Temperature rises causing the death of many animals and plants living near the plant
400
Name the region of the continental US that is the most affected by acid rain
The Northeast
400
Describe the third step in the water purification process
Filtration is used to trap small particles
400
Explain what the 3 R's are and how they can help maintain our supply of both renewable and nonrenewable resources.
Reduce: Use less of the resource Recycle: Instead of adding the resource to a landfill use it to make another product Reuse: Use the same product over and over again
400
The purpose of a nuclear power plant is to produce steam. Explain how the steam is used to produce electricity
The steam causes a turbine to rotate which makes the generator work in turn creating electricity.
400
Identify the greatest problem related to radioactive waste
disposal
500
What was the first thing the US did to help reduce the pollution from smokestacks
Passed laws to make the smokestacks taller
500
Summarize the last 2 steps in the water purification process
Step 4: Chlorination uses chlorine to kill microorganisms Step 5: Aeration is the addition of oxygen to kill more microorganisms and to make the water taste better.
500
Analyze how Earths growing population accelerates the use of Earth's limited resources
What is temperature inversion?
500
After the steam turns the generator, it must be reused. Describe the process needed to recycle the steam
Cold water is pumped in from a cooling tower or river which condenses the steam turning it back to a liquid
500
Explain how scientists could reduce the amount of thermal pollution produced at a nuclear power plant.
Vents, cap, cool the water more before releasing it
