Answer:

The relative method for dating the age of rocks and fossils helps to date the rocks and fossils by determining the approximate age for the fossil or rock by comparing it to something whose age is already known like similar rocks and fossils. In fact, there are certain rocks and fossils which serve as index fossils for comparison.

Absolute dating method tends to determine a precise age of rocks and fossils by radiometric dating of the isotopes of the rocks and fossils.

<h2>Sample Response: </h2>

In the lab, I used the law of superposition, the principle of cross-cutting relationships, and index fossils to determine the relative ages of rock layers. Then, I used a mass spectrometer to find the age and identity of an unknown fossil. I learned that radioactive decay can help scientists figure out the age of rocks and minerals. I also learned that dating rock layers and the geologic time scale can help us understand Earth’s history by identifying what was happening to Earth and what lived on Earth when the rock layers were formed.
