Relative Dating and Stratigraphy

States that younger rocks lie above older rocks if the layers have not been disturbed

• Law of crosscutting
• Law of superposition
• Relative Dating
• Unconformity

A break in the geologic record that is made when rock layers are eroded over a long period of time

• Law of Superposition
• Law of Crosscutting
• Relative Dating
• Unconformity

How does the law of crosscutting explain the age of a fault?

• The fault is younger than the rocks above it.
• The fault is younger than the rocks it cuts through.
• The fault is older than the rocks above it.
• The fault is older than the rocks it cuts through.

What are the relative ages of the features in order from oldest to youngest?

• Limestone, Basalt, Fault, Siltstone
• Siltstone, Fault, Basalt, Limestone
• Limestone, Fault, Basalt, Siltstone
• Limestone, Siltstone, Fault, Basalt
