4. Amy has one older brother and one younger sister. She wants to explain relative dating to them using their ages as an example. Which statement describes their ages using relative dating?

• A. Their ages are 14, 12, and 9.

• B. They are all about the same age.

• C. The girls have different ages from the boy.

• D. Amy is younger than her brother but older than her sister.

5. 5. Which method of finding the relative age of rocks do scientists often use?

• 5. B. Igneous rock is older than nearby sedimentary rock, which is older than nearby metamorphic rock.

• 5. C. Metamorphic rock is older than nearby sedimentary rock because sedimentary rock is deposited before metamorphic rock forms.

• 5. D. The exact age of a sedimentary rock layer can be found using the positions of the layers.
