How are rocks classified?
Scientists observe rock by mineral composition, color, size, and texture and then the rocks are classified into different ways such as metamorphic, igneous, and sedimentary.
Rocks are made up of minerals mixed together. Some rocks don't have more than one mineral. others have tons of minerals. For example, Granite is made up from four different minerals. Quartz, feldspar, hornblende, and mica.
