Vocabulary

 * Solution-** a mixture that has one substance that dissolves in another
 * Vein-** a narrow channel, slab, or tube of mineral that's different from rocks that is lying around it

Processes That Form Minerals

 * Minerals form through crystallization either of melted materials or through crystallization of materials dissolved in water.
 * minerals people use-formed deep in crust for a long time

Minerals From Magma

 * affects size of crystals formed
 * rate magma cools
 * amount of gas contain
 * chemical composition (of magma)
 * slow evaporation= large crystals

Minerals From Hot Water Solutions

 * element form mineral-dissolve in hot water (sometimes)
 * How minerals form by hot water solutions:
 * 1) Magma heats water to a high temperature
 * 2) Dissolved minerals form solutions
 * 3) Hot water solutions cools,the elements and compounds leave the solution and crystallize to form minerals
 * veins form by:
 * metals crystallize underground from solutions
 * How minerals form from solutions __along the mid-ocean ridge__:
 * 1) ocean water seeps go down through cracks
 * 2) water meets high-temperature magma
 * 3) hot water dissolves minerals
 * 4) solution rises out chimneys
 * 5) hits cold
 * 6) crystallize

Minerals Formed By Evaporation

 * minerals form when solution evaporates
 * halite deposits
 * Midwest/Southwest
 * Gulf Coast
 * form when seas evaporate
 * minerals form by evaporation of seawater:
 * gypsum
 * building materials
 * calcite
 * used in microscopes
 * minerals with potassium
 * fertilizer

Where Minerals Are Found

 * crust mostly made of common rock-forming minerals
 * valuable minerals
 * found in/near areas of volcanic activity/mountain building
