Question 1:   The word Geology is a greek word meaning...
"the study of rocks"
"the study of earth"
"the study of space"

Question 2:   Minerals are...
solid materials in which the atoms are arranged in a particular pattern.
rocks that have undergone a change in form or nature as a result of pressure or heat.
always naturally occurring, homogeneous, inorganic solids.

Question 3:   Crystals are...
solid materials in which the atoms are arranged in a particular pattern.
like rocks only shinier.
always naturally occurring, homogeneous, inorganic solids.

Question 4:   Homogeneous means...
resistance of a mineral to scratching
inorganic
uniform in structure

Question 5:   Hardness means...
uniform in structure
resistance of a mineral to breaking
resistance of a mineral to scratching

Question 6:   A property is a trait that helps makes identification possible. These are all properties. Which one is not a property of a gem?
structure
hardness
malleability
luster

Question 7:   The Moh Scale was created in 1812 by Frederich Mohs. What does it measure?
The hardness of a mineral.
The specific gravity of a mineral.
A mineral's ability to bend a beam of light.

Question 8:   Which order of minerals on the Moh Scale is correct (from least to greatest)?
gyspum, apatite, fluorite, topaz, calcite, talc, orthoclase, quartz, corundum, diamond
topaz, quartz, corundum, apatite, fluorite, diamond, gypsum, talc, calcite, and orthoclase.
talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, diamond

Question 9:   Why did Mohs choose these minerals? (best answer)
They were the only ones that worked.
They were fairly common.
He liked those 10.
The scale was completely linear.

Question 10:   What is diamond often used for (besides jewelry)?
All choices given are correct.
for surgical tools
saw blades
drill bits

Question 11:   Quartz, topaz, and corundum can all do what?
scratch glass easily
scratch diamond easily
easily be scratched by a knife
can not be scratched by a knife.

Question 12:   On the Moh Scale a fingernail is...
3
2.5
1
7.5

Question 13:   How about glass?
4-5
7-8
6-7

Question 14:   Why wouldn't you make a driveway out of a mineral with a 2 on the Moh Scale?
It would be impossible to make it the right shape because it would be to hard.
It would be too slippery. The car wouldn't be able to get up.
It would be very soft--the car would leave tracks in it (and break it obviously).

Question 15:   The scratch test is used to...
identify a mineral.
find out where a mineral is on the Moh Scale.
find out where a mineral is on the Moh Scale AND/OR identify it.
