You are trying to identify two different minerals that are clear. What test would NOT be helpful in identifying the minerals?
a) Determine if the mineral has luster.
b) Determining if the mineral has cleavage or fracture
c) Finding the hardness of the minerals using the hardness test.
d) The streak test because the streak will most likely be colorless.
Moh's Hardness scale runs from 1-10. If a mineral has a hardness of 8-9 what would that tell you about the mineral's hardness?
a) It is easy to scratch. You could scratch it with your fingernail.
b) It it is not easily scratched and is high on the hardness scale.
c) The scale doesn't go up to 8 or 9.
d) The hardness can't be determined if you have an 8 or 9.
How would you perform the streak test?
a) Try to write with the mineral on your paper.
b) Take the mineral and see if you can scratch it with different items.
c) Using a streak plate run the mineral over the plate to identify the minerals true color b/c minerals can be effected.
d) This is not a test that you can use to identify minerals.
What is s substance made of 2 or more elements that have joined or bonded?
a) Element
b) Compound
c) Density
d) Mineral
How would you perform the hardness test?
a) Use the Mohs Hardness Scale to identify a mineral. You scratch the mineral with different materials to determine it's level.
b) Pick it up in your hand and see if it is solid. If it is, then it is hard.
c) Start with the hardest material you have then work your way backwards.
d) Try and hit it with a hammer, if it doesn't break then it passed the test.
What is the definition of cleavage?
a) A measure of the mineral’s resistance to being scratched.
b) The way a surface reflects light.
c) A tendency of some minerals to break unevenly along curved, jagged or irregular surfaces.
d) A tendency of some minerals to break along smooth, flat surfaces.
What is a naturally formed, inorganic solid that has a definite crystalline structure?
a) Crystal
b) Density
c) Mineral
d) Compound
What is a measure of how much matter is in a given amount of space?
a) Density
b) Compound
c) Fracture
d) Cleavage
If you want to try and identify a mineral you could use what type of test?
a) One test you could do would be to test the hardness of the mineral.
b) You could ask Mr. Lee
c) You could throw it against the wall
d) You could ask Sheldon Cooper (who thinks Geology is not a REAL science!)
To determine a minerals luster you would:
a) Use a magnet to see if the mineral has magnetic properties.
b) Look at the color of the mineral to determine what kind of mineral it is but THIS IS THE MOST UNRELIABLE.
c) Determine if it is metallic or nonmetallic. There are many different type of luster.
d) You could look up the density of the mineral.
This is a pure substance that cannot be broken down or separated into simpler substances by chemical means. All minerals contain 1 or more of these.
a) Element
b) Compound
c) Crystal
d) Density
The color of the mineral in a powdered form made by writing with the mineral is called?
a) Streak Plate
b) Streak
c) Hardness
d) Breakage
A mineral's resistance to being scratched is called?
a) Cleavage
b) Fracture
c) Hardness
d) Streak
The way a mineral or substance reflects light is called?
a) Mineral
b) Pretty
c) Streak
d) Luster
What is a tendency of some minerals to break unevenly along curved, jagged or irregular surfaces?
a) Fracture
b) Cleavage
c) Luster
d) Hardness
The following are test you can perform to identify unknown minerals:
a) Streak, Color, Luster, Heat, Hardness, Density, Cleavage
b) Streak, Color, Magnetism, Breakage, Melting Test, Density
c) Streak, Color, Luster, Hardness, Water test, Breakage
d) Streak, Color, Luster, Hardness, Magnetism, Breakage, Density.
A streak plate is made out of:
a) Ceramic tile. It is used to find the minerals true color.
b) Unglazed porcelain. It is used find the minerals true color because minerals are affected by air and water.
c) Glass. It is used to find the minerals true color.
d) A streak plate is a figment of your imagination. You must be working really hard!
Is it important to conduct more than one test to identify an unknown mineral?
a) Yes, because minerals can't be identified.
b) Yes, because 2 minerals can have the similar physical properties like color or metallic luster.
c) No, because all you need to know is the minerals color to be able to identify an unknown mineral.
d) No, because all you need to know is if the mineral has luster.
To determine if a mineral has breakage you would:
a) You scratch it with different minerals to determine it's breakage.
b) You chip off a piece of it to see how it breaks.
c) You can rub it on a streak plate to see what the color of the mineral would be.
d) Look at it with a magnifying glass to determine if it has cleavage or fracture.
If I study the study guide and my foldable for my minerals test I will most likely...
a) Fail... studying never helps anyone. THIS IS THE WRONG ANSWER!!!
b) Get an A!
c) What there is a test?
d) I don't know... I can't predict the future.
