Geologic Time Quiz 1

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

• Law of crosscutting
• Law of superposition
• 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.

Relative dating of rock layers tells us that the deeper we dig, _______.

Which of the following is the oldest?

Used to determine whether an object is older or younger than other objects
