- 19. Multiple Choice
Physical properties of minerals such as color, luster, hardness and streak are used to determine what about a mineral?
Identity
Mass
Age
Location
- 20. Multiple Choice
How are minerals identified using luster?
Minerals are scratched against each other. The mineral that does the scratching has the most luster.
Using a balance, the mass is recorded. Which mineral has the largest mass has the most luster.
They are rubbed together on unglazed tile. The powder left behind is luster.
The way the light reflects off a mineral determines the luster of the mineral.
- 21. Multiple Choice
When determining which mineral will scratch other minerals, you would need to refer the:
Periodic Table of Elements
Rock Guide Book
Mohs Hardness Scale
Richter Scale
- 22. Multiple Choice

The mineral can scratch Apatite and every mineral with a hardness scale number lower than 7.
The mineral cannot be scratched by Apatite, but can be scratched by Feldspar.
The mineral can scratch Calcite, but cannot scratch Apatite.
The mineral can scratch Apatite and every mineral with a hardness scale number higher than 7.
- 23. Multiple Choice
