What is the Law of Superposition?

Back

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

How can you determine the relative age of rock layers?

Back

You can determine the relative age of rock layers by using the Law of Superposition, examining the sequence of layers, and identifying any disturbances such as faults or intrusions.

What does 'relative dating' mean in geology?

Back

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

Front

What is an intrusion in geology?

Back

An intrusion is a body of igneous rock that forms when magma pushes into pre-existing rock layers and solidifies.

Front

What is a fault?

Back

A fault is a fracture or zone of fractures in the Earth's crust along which movement has occurred.

What is the significance of fossils in rock layers?

Back

Fossils help to date rock layers and provide information about the environment and conditions when the layers were formed.
