Rocks - are made of two or more minerals
Crystal - solid material with atoms arranged in a repeating pattern

4. As magma cools, atoms combine in orderly patterns to form minerals
As magma cools, atoms combine in orderly patterns to form minerals. Minerals also form from melted rock that reaches Earth's surface or lava.

6. Minerals that split into pieces with smooth, regular planes that reflect light are said to have cleavage.
Minerals that break into pieces with jagged or rough edges have fracture.

12. Igneous - Rock formed when molten (melted) materials harden.
Sedimentary - Rock formed from sediment (sand, mud, animal remains, etc) on the surface of the earth
Metamorphic - Rock that has been physically altered by heat and/or pressure.
