Which statement is true?

• Minerals that have weak bonds fracture.

• Minerals that have high densities always have fracture.

• Light-colored minerals always have cleavage.

What determines a mineral’s luster?

• its streak

• the shape of its crystals

• its chemical composition

• the way in which it forms

A mineral’s hardness is determined by its

• cleavage or fracture pattern.

• luster and the color of its streak.

• composition and arrangement of atoms.

• crystal shape and the way it formed.
