Explanation:
Rocks are classified as aggregates of minerals, and they can contain a combination of different minerals. In fact, most rocks are made up of more than one mineral. For example, granite is a common type of rock that is made up of minerals such as quartz, feldspar, and mica. So, it is not accurate to say that all rocks are made up of only one mineral.
