Relative Dating

The Law of Superposition helps scientists to determine what?

• The absolute age of rock layers
• The age of fossils
• The relative age of rock layers
• the super powers of rocks

What is the correct order of the rock layers from oldest to youngest?

• F, E, C, B, A, D

• F, E, D, C, B, A

• A, B, C, D, E, F

• D, F, E, C, B, A

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.

How does sedimentary rock usually form?

• Vertically
• Diagonally
• Folding
• Horizontally

According to the law of superposition, which layer is the youngest?

• A
• B
• C

The age of a rock compared to the ages of other rocks is the rock's

• absolute age
• geologic age
• sedimentary age
• relative age

How do geologists use relative dating?

• Placing rocks in order from youngest to oldest
• Placing rocks in order by minerals they contain
• Classifying rocks by different textures
• Classifying rocks by different isotopes

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

_{Which rock layer in the diagram seems to be the oldest?}

• F
• E
• B
• A
