Geologists analyze the positions of rock layers to determine their age and identify how they change over time. To do this, they use the law of what?
Understand the Problem
The question is asking about the principles that geologists use to analyze rock layers for their age and changes over time. Specifically, it refers to a law that aids in this analysis.
Answer
superposition
The final answer is superposition.
Answer for screen readers
The final answer is superposition.
More Information
The law of superposition is a principle in geology where, in any undisturbed sequence of rocks, the oldest layers are at the bottom, and the youngest layers are at the top.
Tips
A common mistake is confusing the law of superposition with other geological principles like the geological record.
