A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure. Minerals are formed through geological processes and can be found in various environments, such as the Earth’s crust, ocean floors, and even in meteorites. They possess specific physical properties, including hardness, color, luster, and cleavage, which help in their identification. Minerals are classified into different groups based on their chemical composition, such as silicates, carbonates, and oxides. They play a vital role in various industries, including construction, electronics, and agriculture, and are essential for human health and environmental sustainability.
