How do mineral contribute to the rock composition?

Minerals are the building blocks of rocks, as they are naturally occurring inorganic substances with a defined chemical composition and crystalline structure. The specific combination and arrangement of minerals within a rock determine its type, properties, and appearance. For example, igneous rocks are primarily composed of minerals like quartz and feldspar, while sedimentary rocks may contain minerals like calcite and clay. The mineral content influences factors such as color, hardness, and texture, which are essential for identifying and classifying different rock types.
