Characteristics of Minerals
- Solid – All minerals will be solids at normal temperatures on Earth.
- Naturally occurring – Minerals occur in nature.
- Inorganic – Minerals don’t come from plants, animals, or other living organisms.
- Fixed chemical structure – Specific minerals will always have the same chemical formula.
What are the 8 properties of minerals?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
What are the big 8 minerals?
The abundance and diversity of minerals depend on the abundance in the Earth’s crust of the elements of which they are composed. Eight elements make up 98% of the Earth’s crust: oxygen, silicon, aluminium, iron, magnesium, calcium, sodium and potassium.

What are 2 facts about minerals?
Minerals are always solid and have a distinctive geometric shape called a crystalline structure. Each kind of mineral has the same set of chemicals in its make-up. The mineral quartz always contains two oxygen atoms for every silicon atom. Mineral crystals are so small that they can only be viewed under a microscope.
What are minerals for kids?
Minerals. make up Earth’s rocks, sands, and soils. They are found on Earth’s surface as well as deep underground. Minerals are inorganic substances, meaning that they do not come from an animal or a plant. Mineralogy is the science of minerals.
What color are minerals?
Minerals are colored because certain wavelengths of incident light are absorbed, and the color we perceive is produced by the remaining wavelengths that were not absorbed. Some minerals are colorless. This means that none of the incident light has been absorbed.

What are three fun facts about minerals?
All minerals are inorganic because they are made of nonliving particles. Minerals are always solid and have a distinctive geometric shape called a crystalline structure. Each kind of mineral has the same set of chemicals in its make-up. The mineral quartz always contains two oxygen atoms for every silicon atom.
What is the oldest mineral found on Earth?
Zircons
Zircons, the oldest minerals on Earth, preserve robust records of chemical and isotopic characteristics of the rocks in which they form.

What is true about rocks and minerals?
Rocks are comprised of minerals, but minerals are not comprised of rocks. Minerals are inorganic compounds with unique chemical structures and physical properties that occur naturally. Rocks are solid masses that don’t naturally occur. For example, the minerals quartz and feldspar , when formed together, make granite, which is a rock.
Can you identify my rock or mineral?
Can you identify my rock or mineral? Rocks and minerals must be examined in person from all perspectives for accurate identification; they are extremely difficult to identify through photographs. You will get the best results by taking your rock or mineral to a local source where it can be handled and examined closely.
