Earth materials that are classified as minerals exhibit 5 specific characteristics. In your
own words, describe the 5 key characteristics of a mineral.
Your Answer:
1. Solid form - Minerals are typically solid substances at normal temperatures and
pressures. They are not liquids or gasses.
2. Naturally Occurring - They must be naturally formed by a geological process.
Minerals cannot be man-made in a laboratory.
3. Inorganic - Minerals are not derived from living organisms. They do not come from
plants or animals.
4. Definite Chemical Composition - Each mineral has a specific chemical composition,
which means it is composed of a set combination of elements.
5. Crystaline Structure - Minerals have an ordered, repeating atomic structure, often
forming crystals. This structure gives minerals their characteristic shape and properties.
