• absolute time (dating)

• 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

Which method of radioactive dating would you use on a bone thought to be around 40,000 years old.

• Carbon-14

• Uranium-238

• This bone could not be radioactively dated, it is too young.

• This bone could not be radioactively dated, it is too old.

• z

• y

• w

• there is no match

What is the best reason that fossil #4 is NOT a good index fossil?

• It is not widespread

• It is in half of the outcrops

Sedimentary rocks are used for

  only

• relative dating only

• both absolute and relative dating
