34
Q

What is a mineral?

A

A naturally formed, inorganic solid that has a crystalline shape.

35
Q

A

False

37
Q

What is the meaning of inorganic?

A

Never alive

38
Q

A

Physical Properties

40
Q

What are the 5 different ways you can identify a mineral by its physical properties?

A

Color / Transparency
Luster
Streak
Hardness
Cleavage / Fracture

41
Q

What is the first thing noticed in the mineral?

A

Color / Transparency

42
Q

Q

What would a translucent mineral look like?

A

Milky

44
Q

What would an opaque mineral look like?

A

Not see through

45
Q

What is luster?

A

The way it reflects light

46
Q

What does it mean if a mineral is metallic?

A

The color of the powdered form of the mineral

49
Q

How do you find the streak?

A

Rub the mineral against the streak plate - different minerals leave different colors
