10. A museum is creating a new geology exhibit about rocks from South America. The museum curator is working on the information labels for two different rock
samples. The information on the labels is as follows:
• Rock A formed from small pieces of rock.
• Rock B formed from liquid rock in a different place.
• Rocks A and B formed at about the same time.
The curator wants to put information about rock type on the labels. Are Rocks A
and B the same or different types of rock?
The rocks are
a the same type because they both formed from rock material.
b the same type because they formed at the same time.
c different types because they formed in different places.
d different types because they formed in different ways.
