Mineral Basics
One of the 4: Not made by humans; God created
Naturally Occurring
What hot, melted rock inside the Earth is called.
Magma
The color of the powder left behind when a mineral is rubbed on a tile.
Streak
Describes how light reflects off a mineral (metallic or nonmetallic).
Luster
Minerals mined because they contain useful substances.
Ore
One of the 4: All minerals are in this state of matter.
Solid
The crystal size produced when magma cools very quickly.
Small
The property that measures how easily a mineral can be scratched.
Hardness
The term for a mineral breaking along smooth, flat surfaces.
Clevage
Minerals valued primarily for their beauty and rarity.
Gems
One of the 4: Term meaning a substance does not come from living things.
Inorganic
The crystal size produced when magma cools slowly deep underground.
Large
This mineral property is not reliable to use by itself for identification.
Color
The term for a mineral breaking in an irregular, rough way.
Fracture
The primary metal extracted from bauxite ore.
One of the 4: Having atoms arranged in a repeating pattern gives a mineral a definite one of these.
Definite Chemical Composition
The primary factor that determines the shape of a mineral's crystal.
The internal arrangement of its atoms - crystal structure.
Why color alone is not a reliable identification tool for minerals.
Because some minerals can have the same color.
The luster type of a mineral that shines like polished metal.
Metalic
Name three major industrial or real-world uses for titanium.
Golf clubs, medical equipment, prosthetic limbs, car parts, bikes, jewelry....
The four core requirements that define any mineral.
The Four Characteristics of Minerals
What happens to dissolved mineral atoms when magma cools down.
Solidification - Atoms loose (thermal) energy, slow down, bond, and arrange themselves into orderly crystal structures.
The mineral hardness scale used to rank scratch resistance from 1 to 10.
Mohs Scale
The distinction between cleavage and fracture in terms of atomic bonds.
The strength of the atomic bonds
Name two common ores mined specifically for titanium.
Rutile Ilmenite
