apply the law of superposition calculate the rate of radiometric decay apply the law of crosscutting relationships calculate the rate of tectonic plate movement
I gave my students this multiple choice question: A hillside along a highway has exposed layers of undisturbed sedimentary rock. Which method would be best for scientists to use to determine the relative age of these sedimentary rock layers?

Only one answer is correct among these 4 choices:
- apply the law of superposition
- calculate the rate of radiometric decay
- apply the law of crosscutting relationships
- calculate the rate of tectonic plate movement

Could you tell me which one is correct?
