This rock diagram has a line running through with arrows pointing in the direction of rock movement.  What does the line represent?

• A fold
• A fault
• A tilt
• An intrusion

The principle that a fault or body of rock is younger than any other body of rock that it cuts through is known as what?

• relative age
• law of crosscutting relationships
• varve
• law of super position

How does absolute age differ from relative age?

• only absolute dating indicates which rock is older than another
• only absolute dating finds the age in years
• only relative dating finds the age in years

Scientists use radioactive decay to measure...

• absolute time

• cross-cutting time

• time of day
