ES Unit 9 Review

Correctly label the mineral properties as to how to test them. Match the following:

• Test A

• hardness

• scratch (Test C)

• cleavage

• Test B

• streak

How do minerals form?

• Minerals form through crystallization from magma, precipitation from water, and biological processes.

• Minerals form through nuclear fusion when the chemical compounds solidify after a reaction

• Minerals form through evaporation from air and precipitation that falls to the ground, solidifying into crystal

• Minerals form through combustion of organic matter which leaves behind a mineral residue that hardens

Which of the characteristics below define a mineral? Choose three.

• Naturally occurring

• Definite chemical composition

• Random internal structure

• Inorganic

An example of an ore mineral includes- (choose three)

• Gallena

• Granite

• Diamonds

• Sulfur

Explain the difference between cleavage and fracture in minerals.

• Cleavage is the way a mineral breaks with irregular surfaces, while fracture is the way a mineral breaks along flat surfaces.

• Cleavage is the way a mineral breaks into small pieces, while fracture is the way a mineral breaks into large pieces.

• Cleavage is the way a mineral breaks along flat surfaces, while fracture is the way a mineral breaks with irregular surfaces.

• Cleavage is the way a mineral breaks with smooth edges, while fracture is the way a mineral breaks with jagged edges.

Pair the common minerals below with its use.

• Diamond

• Coins and electrical wires

• Quartz

• Batteries and ammunition

• Galena

• Glass and computer chips

• Copper

• Jewelry and cutting tools

Using the Mohs Hardness Scale, name two minerals harder than Fluorite.

• A. Talc and Calcite

• B. Quartz and Feldspar

• C. Gypsum and Quartz

• D. Diamond and Talc
