Minerals

Minerals are naturally occurring inorganic substances with a distinct chemical composition and a crystalline structure. They are the building blocks of rocks and are formed through various geological processes. Minerals play a crucial role in the Earth's geology and have numerous practical applications in our daily lives.

Characteristics of Minerals

• Naturally Occurring: Minerals are formed by natural geological processes, without human intervention.
• Inorganic: They are not formed from living organisms or their by-products.
• Distinct Chemical Composition: Each mineral has a specific chemical formula that determines its composition.
• Crystalline Structure: Minerals have a regular and repeating arrangement of atoms, leading to a crystalline structure.

Mineral Identification

Minerals can be identified and classified based on their physical properties, such as color, luster, hardness, cleavage, and specific gravity. These properties help geologists and mineralogists distinguish one mineral from another.

Practical Applications

Minerals have numerous practical applications in various industries. For example, quartz is used in glassmaking, talc is used in the production of cosmetics and pharmaceuticals, and copper is utilized in electrical wiring due to its excellent conductivity.
