When determining the color of a minerals powder, what tool would you need?

• Streak Plate

• Hand Lens

• Microscope

• Triple-Beam Balance

When determining which minerals will scratch other minerals, you would need to refer to the:

• Periodic Table of Elements

• Rocks Guide Book

• Mohs Hardness Scale

• Richter Scale

Which indicator would not be good as the only indicator when identifying a mineral?

• Color

• Breaking Patter

• Specific Gravity

• Hardness

Fracture or cleavage of a mineral tells you the:

How would you determine a mineral's streak?

• The colored powder left behind after rubbing the mineral across a streak plate.

• The colored powder left behind after scratching the mineral with another mineral.

• The breakage pattern of a mineral after being rubbed across a streak plate.

• The breakage pattern of a mineral after being scratched by another mineral.

What are the two main types of luster?

• Cleavage and Fracture

• Metallic and Nonmetallic

• Colored and Clear

• Igneous and Metamorphic

How is specific gravity or density used in identifying minerals?

• Specific gravity allows us to compare the hardness of minerals by seeing which one scratches the other.

• Specific gravity is always changing, so scientists are able to adapt their understanding of mineral properties.

• Specific gravity does not change, so it is a good indicator when identifying minerals.

• Specific gravity tells us where minerals can be found for mining.

Which of the following is a common use of minerals?

• Electronics

• Gemstones

• Building Materials

• All of these

Which mineral is number 8 on the hardness scale?

• Corundum

• Quartz

• Topaz

• Orthoclase
