Introduction to Mineral Identification

The color of a mineral in powder form is called the mineral's 

• hardness
• specific gravity
• luster
• streak

What is the luster of mineral P?

• metallic

• nonmetallic

• hard

• fracture

What type of streak does mineral B leave?

• color
• nonmetallic
• colorless or white 
• cleavage

Which property can you use to distinguish mineral K from mineral O?

• streak
• hardness
• Cleavage or Fracture
• luster

____________ is determined by scratching a mineral with other minerals.

• fracture
• hardness
