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. radiometric dating is getting an age for geologic materials or measuring the age of geologic materials. A fossil is the remains of an animal that existed millions of years ago in a specific type of rock. 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. When an animal or a larger species dies out. A fossil record is a timeline or history that is composed of by fossils. A mold fossil is dissolved by underground water and it has no internal structure. a paleontologist finds fossils or studies fossils and where they came from, what animal they were, etc.
