1

What is the definition of a mineral?

Minerals are naturally occurring, organic, crystalline solid, and chemical element or compound.

2

What mineral is made up of one kind of element?

Native Mineral

3

Define Streak Testing Physical Property of Minerals

Uses a porcelain plate, rub against the plate, gives the true color, not the same as physical color

4

Define Luster Testing Physical Property of Minerals

Amount of light and quality of light reflected

5

Define Crystal Shape & Growth Testing Physical Property of Minerals

Microscopic, large, and Accretion or the growth of minerals

6

Define Hardness Testing Physical Property of Minerals

Uses the Molis hardness scale from 1 to 10, diamond is the hardest and Tak is the softest

7

Define Flame Testing Physical Property of Minerals

Uses powder from the mineral, put in a flame and observe the color

8

Define Acid Testing Physical Property of Minerals

Put acid in mineral and see if the mineral dissolves it

9

Define Magnetism Testing Physical Property of Minerals

Place a magnet near the mineral and see if the object magnetizes to the mineral
