Minerals And Rocks Flashcards
Rounded, hollow rock that is often found with mineral crystals
Geode
Process by which Adams are arranged to form a material with a crystal structure
Crystallization
Name two ways minerals can form
- crystallization of magma and lava
2. Crystallization of materials dissolved in water
Minerals form as hot magma cools inside the crust, or as lava hardens on the surface.
Crystallization of magma and lava
When elements and compounds that are dissolved in water leave a solution crystallization occurs
Crystallization of materials to dissolve in water
Some minerals form when_______.
Solutions evaporate
Pure metals that crystallize form Hot water solutions underground often form_________.
Veins
A narrow channel or slab mineral that is different from the surrounding rock
Veins
_________ are the source of gemstones, metals and a variety of materials used to make many products.
Minerals
A rock that contains a metal or other useful mineral that can be mind and sold at profit?
Ore
How do you produce metal from a mineral?
- Rocks containing minerals must be located through prospecting
- Ore deposits are removed from the ground through mining
- Rock is processed by smelting to produce metals
Naturally occurring in organic solid that has a crystal structure and a definite chemical composition.
Mineral
Name the five characteristics of a mineral
- Must be formed by the process that occur in the natural world
- Must be organic meaning that it cannot come from materials that were once part of a living thing
- A solid
- Particles that make it up line up in a repeating pattern which form a crystal
- Has a definite chemical composition or range of compositions
Used to identify a few minerals that have their own characteristic coloring
Color
Color of a minerals powder
Streak
How light is reflected from a mineral surface
Luster
Each mineral has a characteristic density
Density
Using the Mohs hardness scale this scale ranks 10 minerals from softest to hardest
Hardness
Crystals grow atom by atom to form a particular structure, these structures are grouped into six different categories based on the number and angle of Crystal faces
Crystal system
If I mineral breaks easily a long flat surfaces
Cleavage
When a mineral breaks apart in an irregular way
Fracture
Special properties can also be used such as _________ and ability to glow under an ultraviolet light
Magnetism
Name the characteristics that help identify a mineral (8)
Color Streak Luster Density Heartedness Crystal system Cleavage Fracture
