RELATIVE DATING

Front

What is Relative Dating?

Back

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

What does the Law of Superposition state?

Back

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.

Front

What is an Unconformity?

Back

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.

Front

What is Faulting?

Back

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

Front

What is Folding in geology?

Back

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

Front

What is an Igneous Intrusion?

Back

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

Front

What part of an organism is most likely to become a fossil?

Back

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

Front

What is the significance of Fault E being younger than Intrusion D?

Back

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

Front

How can geologists determine the relative ages of rock layers?

Back

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

Front

What is the Law of Crosscutting Relationships?

Back

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