Lab Practical Review on Minerals

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

• cleavage and color

• luster and color

• hardness and streak

• streak and cleavage

Which mineral will scratch fluorite, galena, and pyroxene?

• graphite

• calcite

• olivine

• dolomite

The Luster of a mineral means:

• How it reflects light

• How awesome it is

• How hard the mineral is

• What color the mineral is

If a Mineral has a Metallic Luster it looks

• glassy

• waxy

• like a metal

• putty

If a mineral has a Non-Metallic Luster it:

• Looks like a metal

• Doesn't look like a metal

• Looks glassy

• Looks shiny

A Mineral's Hardness is determined by:

• The color of the mineral

• The colored powder left behind

• Its Luster

• It's ability to not be scratched

A mineral's Streak is:

• The color of the mineral

• The colored powder left behind by a mineral

• The mineral's hardness

• The mineral's Luster

A mineral's Streak is tested by:

• Scratching it on glass

• Breaking it

• Rubbing it on a porcelain plate

• Staring at it

A mineral's Hardness is determined by:

• Scratching it on glass

• Rubbing it on a porcelain plate

• Breaking it

• Staring at it

Base your answer on the diagram below, which shows three minerals with three different physical tests, A, B, and C, being performed on them.

• A—cleavage; B—streak; C—hardness

• A—cleavage; B—hardness; C—streak

• A—streak; B—cleavage; C—hardness

• A—streak; B—hardness; C—cleavage
