Some Minerals can be detected by a little more features than the naked eye. By doing this, we can examine the physical properties of the mineral. These features include the following:
- Color: Mineral color
- Streak: The color of the mineral powder (often different from the color of the whole mineral).
- Diaphaneity: Transparency
- Density: Mass in volume is usually called "specific gravity" (or specific gravity). This density is measured relative to the density of the water reference material.
- Foliating: The mineral tends to crack along weak surfaces.
- Fracture: The pattern by which a mineral is broken.
- Hardness: It presents which minerals can be scratched. Minerals are everywhere. Scientists have identified more than 4,000 minerals in the Earth's crust, although most of the Earth's crust is made up of several.
A mineral has the following properties: It must be solid. It must be crystalline, meaning it has a repetitive arrangement of atoms. It should occur naturally. It must have a specific chemical composition.
