What are the 4 questions you need to ask to find out if a substance is a mineral?
To make a substance non-living, what is not allowed?
Rare minerals that can be cut and polished.
Contains enough useful material that it can be sold for a profit.
1. Unique crystal structure (all crystals have an orderly pattern of atoms).
2. The way the mineral breaks.
3. Color or Streak.
5. Moh's Scale Of Hardness.
What five properties are used to identify Minerals?
An orderly pattern of atoms.
What do all crystal have?
What are the two ways Minerals break?
Minerals that split into pieces with smooth, regular planes that reflect light.
Minerals that break into pieces with jagged, rough edges.
Color of powdered mineral.
Define Color or Streak:
How light reflects from surface.
What are 4 examples of Luster:
Classifies Minerals from 1 (Softest) to 10 (Hardest).
Define Moh's Scale Of Hardness:
On the Moh's Scale Of Hardness, what Mineral is #1 (Softest)?
On the Moh's Scale Of Hardness, what Mineral is #10 (Hardest)?
True or False: When doing a Streak Test, the color of the mineral powder will be the same color as the mineral.
