Relative Dating

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.

Analyze the seashell found in the white layer.  Which statement is true of the rock layer that contains this fossil?

• It could also contain a fossil from the bottom layer.
• It is older than the layers below it.
• It is younger than the layers above it.
• It is older than the layers above it.

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

• the younger the rocks get
• the smellier the rocks get
• the harder the rocks get
• the older the rocks get

According to the law of superposition, the oldest fossils are found 

• At the top of the rock layers
• Near the bottom of the rock layers
• In the middle of the rock layers
• Somewhat near the surface

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