4.2 How Minerals Form
Learning targets
• I can understand how minerals form from
magma and lava.
4.2 How Minerals Form
Learning targets
• I can understand how minerals form from
magma and lava.
• I can understand that minerals form from
water solutions.
4.2 How Minerals Form
Key Terms
• Geode –
A hollow rock inside
which mineral
crystals have grown
4.2 How Minerals Form
Key Terms
• Crystallization
The process by
which atoms are
arranged to form a
materials with a crystal
structure.
4.2 How Minerals Form
Key Terms
• Solution –
A mixture in which one
substance is dissolved in
another.
4.2 How Minerals Form
Key Terms
• Vein – A narrow
deposit of a mineral
that is sharply
different from the
surrounding rock.
4.2 How Minerals Form
Minerals from Magma and Lava
• As hot magma cools inside the Earth’s
crust the molten materials harden into
minerals.
4.2 How Minerals Form
Minerals from Magma and Lava
• As hot magma cools inside the Earth’s
crust the molten materials harden into
minerals.
–When magma cools quickly the crystals
are tiny
4.2 How Minerals Form
Minerals from Magma and Lava
• As hot magma cools inside the Earth’s
crust the molten materials harden into
minerals.
–When magma cools quickly the crystals
are tiny
–When magma cools slowly the crystals
grow larger.
4.2 How Minerals Form
Minerals from Magma and Lava
When magma cools slowly the crystals
grow larger.
-The bigger the crystal the longer the
magma took to cool.
4.2 How Minerals Form
Minerals From Solutions
• A solution is a mixture in which one
substance is dissolved in another.
4.2 How Minerals Form
Minerals From Solutions
• When these elements and compounds are
dissolved into water the crystals form
when the water evaporates leaving behind
crystals.
4.2 How Minerals Form
Minerals From Solutions
• Geodes form when water containing
dissolved minerals seep into hollow rocks
and cool.

4.2 How Minerals Form
Minerals From Hot Water Solutions
• Water solutions deep in the
earth are exposed to high
temperatures.
4.2 How Minerals Form
Minerals From Hot Water Solutions
• When the solution cools the
solution cannot hold onto
the dissolved minerals.
4.2 How Minerals Form
Minerals From Hot Water Solutions
• The minerals released create
crystals Like silver and other
pure metals.
