PreAssessment 6.6C & 6.10B

Which of the following describes a test a student could conduct to help identify a mineral?

• Rub the mineral on a white, unglazed tile and observe the color of the material left behind.

• Carefully measure the mass of the sample of the unknown mineral.

• Place the mineral in boiling water in order to identify its boiling point.

• Compare the size of a mineral to the size of a known identiy of another mineral.

Which of these terms might be used to describe a mineral's luster?

• Rectangular

• Heavy

• Glassy

• Magnetic

Provided is a chart of the Mohs Hardness Scale.

Using the Mohs Hardness Scale, determine which mineral can scratch othoclase feldspar.

• Calcite

• Fluorite

• Talc

• Quartz

The table provides data on four different minerals.

A mineral is observed to be black in color, and when it is rubbed on an unglazed tile, it leaves a red powder behind. Which of the minerals in the table is a possible identification for this mineral?

• Chromite

• Hematite

• Graphite

• Bornite

Which of the following correctly describes a test that is used to determine a mineral's identity?

• Use a balance to find the mass of the mineral

• Try to scratch the mineral with an iron nail

• Observe the shape and size of the mineral

• Submerge the mineral in a beaker of water

Igneous rock forms in regions where -

• rock is heated to melting point then cooled to a solid.

• metallic minerals are put under extreme pressure.

• a river deposits sand and mud over a long time.

• evidence of organisms is becoming fossilized.
