Which mineral is commonly known for its crystalline structure and hardness?

• A. Calcite
• B. Quartz
• C. Gypsum
• D. Pyrite

Answer: (B)

Quartz is well-known for its crystalline structure and hardness, which is a defining characteristic of this mineral. It is composed of silicon dioxide (SiO2) and forms in a variety of environments, often creating spectacular crystal formations. The hardness of quartz on the Mohs scale is 7, making it one of the harder minerals commonly found in nature. This hardness enables quartz to resist scratching, which contributes to its use in many applications, including jewelry and electronics. Its crystalline structure, typically exhibiting a hexagonal shape, adds to its distinctive appearance and is sought after in various ornamental and functional uses. This mineral's durability and aesthetic qualities highlight its prominence in geology and industry.
