Study Notes
Vocabulary
- Mineral: Naturally occurring inorganic solid with a definite chemical composition.
- Luster: The way light reflects off a mineral's surface, indicating its shine or sheen.
- Hardness: A measure of a mineral's resistance to scratching, commonly determined using the Mohs scale.
- Cleavage: The tendency of a mineral to break along flat surfaces, resulting in smooth, planar surfaces.
- Fracture: Irregular breaking of a mineral that does not follow smooth surfaces.
- Streak: The color of a mineral's powder when it is scraped across a surface, typically a ceramic tile.
- Magnetism: The ability of a mineral to be attracted to a magnet, indicating the presence of iron or similar elements.
- Density: The mass of a mineral per unit volume, calculated using the formula density = mass/volume.
- Crystallization: The process through which atoms are arranged to form a material with a crystal structure.
- Gem: A hard, colored mineral with a brilliant or glassy luster, often cut and polished for decoration.
- Metal: A material that is typically hard, shiny, and conductive of electricity and heat.
- Ore: A type of rock that contains a metal or other useful minerals that can be economically extracted.
Properties of Minerals
- Five characteristics of minerals include being inorganic, solid, having a definite chemical composition, being naturally occurring, and having a crystalline structure.
- Not all minerals are formed from materials that were once part of living organisms; this statement is false.
- Hardness is measured using the Mohs scale, which ranks minerals based on their ability to scratch one another.
- The property of minerals that describes light reflection from a mineral's surface is luster.
- Cleavage can be differentiated from fracture based on the regularity of surface breaks; cleavage shows flat surfaces while fracture does not.
Mineral Formation and Resources
- A geode is a rounded, hollow rock lined with mineral crystals.
- Crystallization occurs when atoms arrange into a structured format within materials.
- When elements and compounds dissolve in water and are precipitated out, the process is known as crystallization.
- A mineral that is cut and polished, known for its hardness and color, qualifies as a gemstone.
- An ore is rock containing valuable minerals or metals that can be mined profitably.
