Renewable Energy Practice

What is nuclear power used for according to the cheat sheet?

• To create a nuclear reaction for scientific research

• To generate electricity using chemical reactions

• To produce greenhouse gases

• To mine for uranium

Which of the following is a method of generating nuclear power?

• Combustion

• Fission

• Photosynthesis

• Electrolysis

What is a benefit of nuclear energy listed in the cheat sheet?

• High cost

• Produces large amounts of greenhouse gases

• Produces more energy than fossil fuels

• Leads to thermal pollution

What is a drawback of nuclear power mentioned in the document?

• It is a renewable resource

• It produces a significant amount of energy

• It can lead to radioactive waste

• It is based on the fusion of atoms

According to the cheat sheet, how does nuclear fusion differ from nuclear fission?

• Fusion occurs naturally on the sun, while fission does not occur naturally

• Fusion requires uranium, while fission does not

• Fusion produces less energy than fission

• Fusion splits the nucleus, while fission combines nuclei

What is the role of uranium pellets in a nuclear power plant as described in the cheat sheet?

• They are used to cool down the steam

• They are placed in water to start the fission reaction

• They are used to generate steam directly

• They are a byproduct of the fission reaction

What is the definition of the half-life of radioactive material?

• The time it takes for all radioactive material to decay

• The measure of time for half of an atomic nucleus to decay

• The time it takes for radiation levels to reach half of their original value

• The period after which radiation is considered safe

What generally indicates safety in terms of the half-lives of radioactive material?

• One Half-Life

• Five Half-Lives

• Ten Half-Lives

• Twenty Half-Lives

What does the term 'fission' refer to?

• The combining of two nuclei to form a greater nucleus

• The splitting of a nucleus into two smaller nuclei

• A noble gas produced in the ground from uranium

• A chemical element most often used for nuclear power plants

What is 'fusion' in the context of nuclear reactions?

• The splitting of a nucleus into two smaller nuclei

• A noble gas that is produced in the ground from uranium

• The combining of two nuclei to form a greater nucleus

• A chemical element most often used for nuclear power plants
