Rocks and Minerals [rŏks] [ănd] ['mĭn-ûr-'əlz]
Rocks are hard solids made of one or more minerals; minerals are a non-living, solid material with particles arranged in a crystal structure.

Idaho's nickname is the Gem State. Idaho's geology makes it a special place for finding many different kinds of rocks and minerals. Minerals are made from 92 chemical elements that join together in many different ways. A rock is a material made of one or more minerals. There are three types of rocks — igneous, sedimentary, and metamorphic — that have formed over time in the Earth's different layers. A rock can begin as one type and can change many times. It can take thousands of years for rocks to weather and erode. This process of changing is called the rock cycle.
