RELATIVE DATING

Relative dating is a method used to determine the age of rocks and fossils in relation to one another, without determining their exact age.

The Law of Superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest layers are at the top.

An unconformity is a break in the geologic record that occurs when rock layers are eroded over time, leading to a gap in the geological timeline.

Faulting is the process where rocks break and move along a fracture, often causing earthquakes.

Folding is the bending of rock layers due to tectonic forces, which can create hills and valleys.

An igneous intrusion occurs when magma from beneath the Earth's surface pushes into existing rock layers and solidifies.

Bones are the parts of an organism that are most likely to become fossils due to their hard structure.

If Fault E is younger than Intrusion D, it means that the fault occurred after the intrusion, indicating the sequence of geological events.

Geologists use principles such as the Law of Superposition, the Law of Crosscutting Relationships, and the study of fossils to determine relative ages.

The Law of Crosscutting Relationships states that if a rock layer or fault cuts through another layer, the layer that is cut is older.
