or more minerals and organic matter
 Explain
how minerals contribute to rock
composition.
A
mineral is solid, nonliving, crystal-shaped,
and formed in nature, and a rock is made up
of 1 or more minerals. Rock is formed from
1 or more minerals and can become a
sedimentary rock (weathering and erosion),
igneous rock (magma), or metamorphic
rock (heat and pressure).
