Minerals are naturally occurring, solid, and inorganic substances that have a definite chemical composition (or range of compositions) and a regular internal atomic arrangement. Approximately 4,000 minerals have been identified on Earth.

Rocks & Rock Cycles

A rock is a solid, cohesive aggregate of one or more minerals or mineral-like materials (such as volcanic glass).

The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: igneous, sedimentary, and metamorphic. The rock cycle is driven by the combined effects of plate tectonics and surface weathering.

Visit the Limper Geology Museum to see firsthand a wide variety of interesting specimens of minerals and rocks of all kinds.
