Question

16 dr. garcia is a geologist from peru, and dr. ferreira is a geologist from brazil. they are comparing rocks from their areas for their research and have some information about them. the information 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.

as they work on their study they need to answer the question: 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.

Explanation:

Rock A formed from small pieces of rock (sedimentary - like formation process), while Rock B formed from liquid rock (igneous - like formation process). Rock - forming processes define rock types. So, different formation ways mean different rock types.

Answer:

d. different types because they formed in different ways
