by natural processes
• Inorganic solid: Are not alive, were never
part of anything living.
• Solids with Specific Chemical Composition:
solid with a unique chemical composition of
elements
• Definite Crystalline Structure: Atoms
arranged in geometric patterns
Why are Minerals Important?
• Earth’s crust is
composed of about
3,000 minerals.
• Minerals play a role in
forming rocks, shaping
Earth’s surface, and
