Law of Superposition
The Law of Superposition is a principle used in geology and archaeology that states in undisturbed layers of rock or soil, the oldest layers are at the bottom and the youngest are at the top. Think of it like a stack of pancakes: the first one you cooked is at the bottom and the last one is at the top. This law helps scientists and researchers determine the relative ages of different layers and understand the history of Earth and human activities over time.
