Answer
1. Definite Chemical Composition: Minerals are composed of specific chemical elements arranged in a fixed ratio. Each mineral has a distinct chemical formula that defines its composition.
2. Crystalline Structure: Minerals have an ordered internal arrangement of atoms, forming a crystalline structure. This regular arrangement gives minerals their characteristic geometric shapes and physical properties.
3. Inorganic Nature: Minerals are naturally occurring substances that are formed through geological processes. They are not the result of biological or organic activity.
4. Solid State: Minerals exist in a solid state at normal temperatures and pressures. They maintain their shape and rigidity, displaying a definite volume and resistance to deformation.
5. Physical Properties: Minerals exhibit various physical properties, including hardness, cleavage or fracture, color, luster, streak, density, and specific gravity. These properties can be used to identify and distinguish different minerals.
It is important to note that these characteristics collectively define minerals, and any substance that does not fulfill all of these criteria cannot be classified as a mineral.
