The video explains how rock layers form over time due to natural forces like wind and rain. It compares Earth's layers to a sandwich and highlights the Grand Canyon as an example. Fossils, which are preserved remains of plants and animals, are often found in these layers. Paleontologists study fossils to learn about past life forms. The video describes methods to determine fossil ages, including the geologic time scale, relative dating, and absolute dating, with a focus on radiometric dating. Understanding fossil ages helps scientists reconstruct Earth's history.
