How minerals form:
Crystallization is the process where atoms are arranged
to form a material with a crystal structure. When
crystallization happens, minerals are formed.
Minerals can form through crystallization in two ways:
1. Minerals form from magma and lava.
When molten (melted) material cools down, crystallization occurs.
•Magma
Below ground
Cools slowly
larger crystals
•Lava
At/near surface
cools rapidly
smaller crystals
2. Elements or compounds that form minerals can be
dissolved in water to form a solution.
When the particles leave the solution, crystallization occurs.
Minerals can form from solutions in two ways:
•Evaporation
Water with minerals
in it evaporates,
leaving crystals of the
mineral behind.
•Hot Water Solutions
When hot water that
has minerals dissolved
in it cools down,
crystals form.
