Wait, So What’s a Mineral? Mineral – defined by its characteristics DINC

THINK DINC D I N C efinite chemical makeup norganic solid aturally formed rystal structure

THINK DINC Crystal Structure: Particular repeating 3D pattern Determines physical properties

How are they made? Formed in several ways Water evaporates - Leave space between - Water evaporates Hot water cools Molten rock cools Heat and pressure

Water Evaporates

Hot Water Cools

Molten Rock Cools Lava vs. Magma Melted rock above the surface under the surface
