- 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).
