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 am hesitating between 4 options to answer the following question, which option should I choose?
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?
Possibilities:
- apply the law of superposition
- calculate the rate of radiometric decay
- apply the law of crosscutting relationships
- calculate the rate of tectonic plate movement

apply the law of superposition
