Cleavage

• forms when a mineral breaks along smooth, flat surfaces

• forms when a mineral breaks along rough, uneven surfaces

Fracture

• forms when a mineral breaks along rough, uneven surfaces

• forms when a mineral breaks along smooth, flat surfaces

Hardness is

• the color of a mineral in its powdered form

• the way in which a mineral's surface reflects or absorbs light

• a mineral's ability to resist being scratched

Luster is

• the color of a mineral in its powdered form

• the way in which a mineral's surface reflects or absorbs light

• a mineral's ability to resist being scratched

Streak is

• the color of a mineral in its powdered form

• the way in which a mineral's surface reflects or absorbs light

• a mineral's ability to resist being scratched

Color alone is the best way to identify a mineral

• true

• false

Metallic minerals

• Reflect a great deal of light and leave a colorful streak

• Do not reflect a great deal of light but leave a colorful streak

• Do not reflect a great deal of light and do not leave a colorful streak

• Reflect a great deal of light but do not leave a colorful streak

Density is

• the mass of the mineral divided by its volume

• the volume of the mineral divided by its mass

• the specific gravity of a mineral
