Mineral Properties and Groups

The above figure is testing the mineral's-

• cleavage and fracture

• hardness and color

• luster and density

• streak and magnetism

Gavin conducted a mineral identification experiment with an unknown mineral. He found that the mineral looked black, had a black streak, would fracture, and was sub metallic. What mineral did Gavin most likely find?

• Bornite

• Magnetite

• Graphite

• Biotite

A student was given an unknown mineral sample and told the mineral's hardness is approximately 3. This sample could only be what two minerals?

• Bornite or Geothite

• Hematite or Geothite

• Biotite or Bornite

• Graphite or Biotite

The color left behind when a mineral is rubbed against a rough surface is called its-

• streak

• imprint

• trace

• residual color

A naturally occurring, inorganic solid substance with a definite chemical composition and structure is called-

• a mineral

• a rock

• an inorganic matrix

• a building block of crystals

What is a method of identification that involves only visual observations of the mineral?

• Density

• Hardness

• Melting Point

• Luster

Which of the following terms is NOT used to describe luster?

• Pearly

• Metallic

• Glassy

• Beautiful

The minerals a rock is made up of is referred to as its-

• hardness

• texture

• classification

• composition
