The law of superposition is a basic principle in geology that states that in any sequence of undisturbed sedimentary rocks, the youngest rocks are found at the top, while the oldest rocks are found at the bottom. This law is crucial for determining the relative age of fossils and rocks. By comparing the vertical positions of different sedimentary layers and the fossils they contain, scientists can infer the relative chronological order in which they were deposited. Consequently, the law of superposition allows for the construction of a relative geological timeline, showcasing the temporal order of various fossil species and rock formations.
The law of superposition is a basic principle in geology that states that in any sequence of undisturbed sedimentary rocks, the youngest rocks are found on top, while the oldest rocks are found at the bottom. This principle is used to determine the relative age of fossils and rocks. By examining the layers of sedimentary rock and the fossils found within them, scientists can determine the order in which they were formed. The deeper the layer, the older it is, and the fossils found within those layers are also older. This allows scientists to establish a relative chronology of events in Earth's history.
