Outline

 * Process That Forms Minerals**
 * Minerals are formed inside deep of the Earth and can be formed in two different ways
 * One, through crystallization of melted material
 * Two, through crystallization of materials dissolved in water
 * Minerals From Magam**
 * Minerals form as hot lava that cools inside the crust
 * Size of crystals depend on several factors
 * Slow cooling leads to bigger crystal formation
 * Minerals From Hot Water Solutions**
 * First, water goes inside the crust dissolving the minerals
 * Second, the magma heating up the water
 * Third, water comes out and cools making crystals
 * Minerals formed by Evaporation**


 * Minerals can also be formed by evaporation
 * This is formed by salt water evaporating leaving salt crystals
 * Where Are Minerals Found**
 * Earth's crust is mainly made out of many crystals
 * 1800, are California's richest gold deposits
