QUESTION 4

1. Which of the following best defines the relationship between minerals and rocks?

2.		A rock has an orderly, repetitive, geometrical, internal arrangement of minerals; a mineral is a solid mass or aggregate of rocks.
		A rock consists of atoms arranged in a geometrically repetitive structure; in a mineral, the atoms are randomly bonded without any geometric pattern.
