Answer the following questions in your notebook:

1. Why is it important for scientists to be able to determine the relative age of rocks?
2. When do you use the law of superposition?



Answer :

Final answer:

Determining relative rock ages is crucial using the law of superposition and key beds.


Explanation:

The importance of determining the relative age of rocks lies in understanding Earth's history. Scientists use the law of superposition to establish that deeper rock layers are older than those closer to the surface. This principle aids in creating chronological sequences of events in rock formations.

Law of superposition: The concept that deeper rock layers are older than shallower ones, essential for determining the relative ages of sedimentary rocks.

Scientists use key beds to help date rock layers, which are distinct markers that assist in establishing the relative order of rock formations.
