  • How do crystals form?


Mineral formation

Mineral formation

Cooling magma & magmatic solutions

As it cools, minerals solidify (crystallize) at specific temperatures

Geodes – solutions run through crevices in rk, begin to cool, crystallize from outside towards inside.


Precipitation evaporation
Precipitation & Evaporation

  • Evaporation – water turns to gas leaves behind minerals

  • Dead Sea

  • Salt Lake Sea

  • Precipitation – solutions/waters combine or cool – new minerals fall out
