What is a Mineral?
A mineral is a naturally occurring, solid, inorganic substance with a consistent chemical composition and a distinct physical structure. These substances have a chemical formula that indicates the elements present and their relative proportions. Minerals exhibit specific physical properties, including hardness, color, streak, and density, which differentiate them from other naturally occurring substances.
Examples of Minerals:
Igneous rocks: Quartz, obsidian, basalt
Sedimentary rocks: Sandstone, limestone, shale
Metamorphic rocks: Marble, gneiss, slate
Native elements: Gold, silver, copper, iron
Properties of Minerals:
Chemical Composition: The chemical formula of a mineral tells us the elements present and their relative proportions.
Physical Structure: Minerals exhibit distinct physical properties such as hardness, color, streak, and density.
Specific Heat: The specific heat of a mineral indicates its ability to absorb or release heat.
Magnetic Properties: Minerals can exhibit magnetic properties due to the presence of metallic impurities.
Electrical Conductivity: Minerals can conduct electricity in certain circumstances
