There are over 5,000 known types of minerals. Just a few minerals make up most of the rocks we see, though: feldspars, amphiboles, quartz, olivine, garnet, micas, calcite, and pyroxenes.

Rocks are categorized into three main types: igneous, sedimentary, and metamorphic. There are over 4,000 identified minerals on Earth. Common rocks include granite, basalt, limestone, and sandstone.
