Standards Review
Minerals - S6E5. Students will investigate the scientific view
of how the earth’s surface is formed.

composition.
1. Minerals are solids that occur naturally
and have a definite structure and chemical
composition.
A. TRUE
B. FALSE
3. An unknown mineral sample can be
scratched by a knife blade, but not by a
fingernail. According to Moh’s Scale, what
might be the mineral?
A.
B.
C.
D.
DIAMOND
CALCITE
QUARTZ
TOPAZ
2. Which property describes the way a
mineral reflects light?
A. CLEAVAGE
B. EFFERVESCENCE
C. LUSTER
D. STREAK
4. What is the difference between a mineral
and a rock? You may write it in a table or in a
short paragraph.

1. The specific gravity of a mineral compares
its weight with an equal volume of ______.
A. Diamond
B. Water
C. Air
D. Rock
2. An inorganic crystalline solid is formed in a
lab. Why is it not a mineral?
A. It is a solid.
B. It is a crystal.
C. It is not naturally occurring.
D. It is inorganic.
3. Which of the following groups of minerals
is most common in the earth’s crust?
A. Oxides
B. Silicates
C. Ore minerals
D. Sulfates
4. If you found a metallic gold colored
mineral on the ground, which properties of
minerals would best to help you determine
whether the mineral is gold or pyrite (fool’s
gold)? How would you use those properties to
identify the mineral?

4. If you found a metallic gold colored
mineral on the ground, which properties of
minerals would best to help you determine
whether the mineral is gold or pyrite (fool’s
gold)? How would you use those properties to
identify the mineral?
If I found a metallic gold colored mineral on
the ground, I would use the following
properties to determine if it was gold or
pyrite: crystal form, fracture, streak, and
hardness.
I would use the information I gained from the
tests to compare the mineral to a data table
filled with the information about gold and
pyrite.
1. Use the chart above to answer the following question: Alexis wants to identify a
dark, heavy mineral sample she found in the classroom collection. She notices there
are three minerals in a chart in a reference book that might match her sample. Alexis
next observes that her sample mineral has flat, reflective surfaces that break into
boxlike steps. She infers the mineral may be galena. If she is correct, one more test
will verify her inference. Which property would be best for her to observe next?

4. Describe two ways a mineral can form from
a solution. Write your answer.
One way minerals can form from a solution is
through evaporation of water. Another way is
if too much of a substance is dissolved in
water, ions can come together and crystals of
that substance can begin to form in the
solution.
