Welborn Test 10/28

Chapter Test/Test on Minerals

A mineral that is made up of only one element Native Element
Minerals that break at random and with rough or jagged edges Fracture
Most common mineral found in the Earth's crust Quartz
Color, Crystal, Cleavage/Fracture, Luster, Hardness, Streak Mineral Properties
Shape of mineral formed by repeating pattern of atoms. Some mineral have well defined crystals (cube, hexagon, etc.) while others are irregular Crystal
A mineral lacking both oxygen and silicon Non-Silicates
A substance that cannot be broken down into simpler substances by chemical means Element
The way the mineral breaks. Minerals break away along smooth, flat surfaces and every fragment has the same general shape. Cleavage
The color of the streak can be different from the mineral. The color of the powdered form of the mineral. Minerals must be softer than the streak plate. Streak
The number of protons equals electrons Atomic Number
The ore is mined from rocks that have not been exposed too weathering in a tropical environment Bauxite/Aluminum
Scale from 1 (softest) to 10 (hardest). Test by seeing if the mineral can scratch different objects. MOHS Hardness Scale
How easily a mineral can be scratched Hardness
A mineral containing both silicon and oxygen Silicates
Surface reflection Luster
Shiny, like metal Metallic
Least reliable test. Many minerals have the same _____. Color
A naturally occurring inorganic solid, with a crystal shape that repeats itself, and a definite chemical composition (elements are always the same) Mineral
A rock that contains high enough concentrations of a defined substance such as metal, so it can mined for profit. Ore
Most abundant metallic mineral Iron
Dull, non-shiny, surfaced Non-Metallic
Most abundant elements in Earth's crust Silicon, Oxygen
Mass/Volume Density
Naturally formed, inorganic, crystal-like structure, solid structure, specific chemical composition Mineral
All minerals are solids. A solid matter with tightly packed atoms or ions that has a definite shape and volume. Solid
