Natural minerals are solid, inorganic substances that occur naturally in the Earth's crust. They are formed through geological processes and have a specific chemical composition and crystal structure. Common examples of natural minerals include quartz, feldspar, and mica. These minerals are essential components of rocks and play a vital role in various geological and ecological processes. Natural minerals are important resources for many industries. They are used in construction materials, electronics, and even in the production of fertilizers. Additionally, some minerals, like calcite and gypsum, are used in the manufacturing of products such as cement and plaster. Understanding natural minerals helps us appreciate the Earth's resources and their applications in everyday life.
