Why?
a)
_________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________
b)
_________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________
2) _____________________________________
•
A measure of how easily a mineral can be scratched (does not mean if you can break
•
Moh’s Hardness Scale:
the mineral)
_________________________________________________________________________________________________________________
_________________________________________________________________________________________________________________
According to Moh’s Scale:
Softest mineral=_____________________________________
Hardest mineral=____________________________________
3) ______________________________________
• The way a mineral reflects light
The mineral can be described as:
a) Metallic--______________________________________________________________________________________________________
b) Nonmetallic--_________________________________________________________________________________________________
4) ___________________________________________
• The color of the mineral in powder form
How can I test the powder color of the mineral?
--Rub the mineral on a streak plate!
5) ____________________________________________
• When a mineral breaks along a smooth, flat surface
a) based on _________________________ ___________________________
b) describe directions of breaks
