 * 1) What 4 things define a mineral?
 * Mineral has to be solid
 * The mineral has to be naturally occurring (inorganic), and not made in a lab
 * Has to have a definite chemical composite/crystalline structure

An element is simply defined as a pure substance made out of one atom.
 * 1) What is an element?

Over 80 elements, specifically 90 elements
 * 1) How many naturally occurring elements are there?

Minerals with a molecular structure of only one element; examples being Copper, Sulfur, and Diamond. (Molecular structure: The quantity and method of arrangement concerning the molecules in a particular substance; http://www.minerals.net/mineral_glossary/molecular_structure.aspx)
 * 1) What is a native element mineral?

Solid material (created from heating/cooling minerals) whose constituents are arranged in and ordered structure.
 * 1) What is a crystal?

Silicate minerals have silicon and oxygen, while non-silicate minerals do not.
 * 1) What is the difference between a silicate and a non-silicate mineral?

90%
 * 1) How much of the earth's crust is made of silicate minerals?

Oxides, Sulfides, Carbonates, sulfates, halides, and phosphates
 * 1) List and describe the 6 most important classes of non-silicate minerals

Some minerals may have the same/similar color, but at the same time, some minerals have different colors (quratz, for example). You cannot use color as the only way to identify minerals.
 * 1) How can color be a way to identify minerals AND a way that cannot be used to identify minerals?

Vitreous, Resinous, Pearly, Greasy, Silky, Adamantine
 * 1) List and describe the 6 non-metallic lusters

A long, thin line mark = which is the color of the powder (of the mineral)
 * 1) What is streak?
