What are the characteristics that define a mineral? (CHECK ALL that apply.)

• Inorganic (Non-Living)

• Definite crystal structure

• Can be any phase (solid, liquid, or gas)

• Solid

• Organic (from living things)

This image is an example of what kind of mineral test?

• Hardness

• Color

• Streak

• Special Properties

Minerals that split easily into clean angles or planes are said to have...

• Fracture

• Cleavage

• Breakage

• (None of these)

Hardness is the ability to...

• produce a powder when scratched

• describe how light reflects off the surface

• float or sink in a liquid

• scratch another mineral or surface

Minerals where oxygen is combined with metals are...

• Oxides

• Carbonates

• Silicates

• Predicates

The higher the number a mineral is on the Mohs scale is, the __ the mineral is.

• Harder

• Softer

• Less relevant

Which of the following statements is correct between minerals, ores, and gems?

• Minerals are ores that are mined for profit.

• Gems are super common minerals that can be found anywhere.

• Ores are minerals that are mined for profit.

• None of these statements are correct.

How does that rate of cooling affect the size of crystals?

• Slow cooling minerals result in small crystals

• Well-formed minerals are formed from slowly cooled substances.

• Fast cooling results in large crystals.

• The rate of cooling does not affect the size of crystals in a mineral?
