Answer:
- occur naturally
- different minerals have different chemical composition
- they have an specific internal structure
Step-by-step explanation:
Minerals are substances found in nature, formed by a balanced chemical composition, resulting from millions of years of inorganic processes (heat action, pressure, etc.). All minerals are solid, such as feldspar, mica, quartz. Water, despite having a mineral source, is not an ore, as is mercury (which is liquid at room temperature). In other words, a mineral is any homogeneous substance, solid or liquid, of inorganic origin that arises naturally in the earth's crust. Usually with defined chemical composition and, if formed under favorable conditions, will have ordered atomic structure conditioning its crystalline form and its physical properties.
We can summarize the characteristics of minerals in:
- occur naturally
- different minerals have different chemical composition
- they have an specific internal structure
