- B. Tidal power plants are only built in the Arctic
- C. The tidal cycle means energy is available only at specific times
- D. Tidal energy requires nuclear reactors to operate
Answer
The tidal cycle means energy is available only at specific times
Explanation
The correct option is "The tidal cycle means energy is available only at specific times". The tidal cycle means energy is available only at specific times is right because it directly matches Energy resources: Explain why some energy resources are intermittent.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Misunderstanding Intermittent Energy Resources
Students often confuse intermittent energy resources with non-renewable resources, thinking they are the same.
Clarify that intermittent energy resources, like solar and wind, are renewable but depend on environmental conditions, while non-renewable resources, like fossil fuels, are finite.
