1.1 Multiple-Choice Questions

1) Which of the following best defines the relationship between minerals and rocks?
A) A rock has an orderly, repetitive, geometrical, internal arrangement of minerals; a mineral is a
lithified or consolidated aggregate of rocks.
B) A mineral consists of atoms arranged in a geometrically repetitive structure; in a rock, the
atoms are randomly bonded without any geometric pattern.
