Which statement BEST explains why nuclear energy might be a preferred energy source over coal if uranium is considered a nonrenewable resource?A Mining uranium is associated with low hazards.B Uranium produces nuclear waste while coal does not.C Uranium produces higher carbon dioxide emissions.D A small amount of uranium produces a larger amount of energy.

Identify the natural resource that most nuclear fuel comes from. Uranium oreElectricityRadioactivity Coal

Select two statements that are true for the power plants that you've looked at in this lesson.They can use fossil or nuclear fuels as the primary energy resource They use heat to create steam which turns turbines They can use coal or natural gas as the primary energy resource, but not nuclear fuelThe electricity comes directly from radioactive fuel rods

Which of the following energy resources is renewable?BiomassCoalGasNuclear2Which of the following energy resources is non-renewable?GeothermalNuclearBiomassSolar3Which of the following is NOT a disadvantage of the use of fossil fuels for the generation of electricity?The sulphur dioxide which they produce when burnt can cause acid rain and health problemsThey contribute to global warming when burntThey are non-renewableThey are expensive4Which of the following is NOT a disadvantage of the use of nuclear power for the generation of electricity?The uranium (and plutonium) required is non-renewableThe radioactive waste produced has to be stored carefullyThe generation of electricity by nuclear power contributes to global warmingThere is a risk that nuclear power stations could undergo meltdown (and release radioactive material into the environment)5Biofuels are often described as being ‘carbon neutral’.  What does this mean?Their use helps reduce the amount of carbon dioxide which has been released into the atmosphere by the burning of fossil fuelsThey only release neutral carbon atoms when burnt (and not harmful carbon ions)The carbon dioxide which they release when burnt does not contribute to global warmingThe crops from which biofuels are produced absorb carbon dioxide from the atmosphere while they are growing; biofuels release carbon dioxide when they are burnt6Which of the following energy resources can make use of ‘pumped storage’?HydroelectricWindGeothermalWave

Which of the following is not a potential benefit of using more nuclear energy?A.Fuel is easy to move, so there is less pollution from shippingB.More air pollutionC.Proper control can ensure safe handlingD.Cost of fuel is very low

Which occurs in a fission reaction?  Group of answer choicesEnergy is absorbed as a less stable element forms.A new heavier element is formed and energy is released.Energy is converted into mass and forms a heavier element.The nuclei of atoms are split apart and energy is released. Flag question: Question 12Question 121 ptsOne kilogram of uranium can produce as much energy as 16,000 kilograms of coal. Why is the energy output for uranium so much greater than the energy output for coal?Group of answer choicesUranium is more highly purified than coal.Uranium is a highly reactive metal that reacts violently with oxygen when it burns.Uranium undergoes fission and nuclear reactions give off more energy than chemical reactions.Uranium is extremely radioactive and gives off more electromagnetic radiation than burning coal. Flag question: Question 13Question 131 ptsWhich occurs in a fusion reaction between two atoms?Group of answer choicesEnergy is absorbed as a less stable element forms.A new element is formed and energy is released.Energy is converted into mass and forms a heavier element.The nuclei of the atoms are split apart and energy is released.
