• relative time
• absolute time
• half-lives
• time of day

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

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

Using Carbon-14 and radioactive dating we find what type of age of the fossil.

• relative age

• actual/absolute age

• about the age

• the age of extinction
