The Law of Uniformitarianism is used to explain the history of past events on Earth because it's the idea that the same physical laws of today have always existed. A fossil record is a timeline or history that is composed of by fossils. When an animal or a larger species dies out. The type of rock that most fossils are found in a paleontologist finds fossils or studies fossils and where they came from, what animal they were, etc. Cast fossils are created by the hollow spaces of a mold that is later filled with mineral matter. A fossil is the remains of an animal that existed millions of years ago in a specific type of rock. relative dating is the age of the rock layer compared to other layers The law of superposition says each layer of rock is older than the one after or above it, so the further down into the rock layer you go, the older the layers become.
