Minerals Review

All of the following are examples of natural resources except

• plants

• animals

• minerals

• plastic

Differences in hardness between minerals are most likely caused by the

• internal arrangement of the atoms

• external arrangement of flat surfaces

• number of pointed edges

• number of cleavage planes

WHich term describes the color of a mineral in powdered form?

• streak

• hardness

• cleavage

• fracture

Which term describes minerals that break evenly along a smooth surface?

• streak

• hardness

• cleavage

• fracture

Which term describes minerals that break unevenly into irregular pieces?

• streak

• hardness

• cleavage

• fracture

Which term describes how light reflects off of a mineral?

• streak

• luster

• cleavage

• fracture

Which mineral property is illustrated by the peeling of muscovite mica into thin, flat sheets?

• luster

• streak

• cleavage

• hardness

Which formula is used to calculate the density of a mineral?

• Density = volume / mass

• Density = mass x volume

• Density = mass/ volume

• Density = length x width x height

Which two properties are most helpful in distinguishing between galena and halite?

• cleavage and color

• luster and color

• hardness and streak

• streak and cleavage

The internal atomic structure of a mineral most likely determines the mineral's

• color, streak,and age

• origin, exposure, and fracture

• size, location, and luster

• hardness, cleavage, and crystal shape
