Rocks and minerals are natural materials found in the Earth. Minerals are the building blocks of rocks, and each mineral has its own special properties, like color and hardness. For example, quartz is a common mineral that is hard and often clear or white. When many minerals combine together, they form rocks like granite, which is made of quartz, feldspar, and mica. Understanding rocks and minerals helps us learn about the Earth and its history.
