Unit 7 Review

Which of the following is not a physical property scientists use to identify an unknown mineral? Streak Color Boiling Point Luster

If you are told by your teacher that one of the physical properties of a mineral you have been given is that it is metallic, which physical properties would it be describing? Streak Luster Hardness Shape

Which of the following minerals can scratch Feldspar but be scratched by Topaz? Quartz Apatite Corundum Fluorite

If you take a piece of graphite and rub it across a plate to view its color in powder form, what physical property are you testing? Luster Hardness Color Streak

Which of the following is a physical property scientists use to identify an unknown mineral? Streak Melting Point Luster Hardness

How are minerals identified using Luster? Minerals are scratched against each other. They are rubbed against an unglazed tile. Using a balance scale and finding the mass. The way the light reflects off of a mineral.

Sarah was taking a walk with her friends. She looked down and saw two unknown minerals. When she dragged them across the sidewalk, she noticed that they produced the same color mark, but one scratched the other. What conclusion could Sarah draw? Their hardness and streak were the same. Their hardness is the same and their streak is different. Their streaks are the same, but their luster is different. Their hardness is different, but their streaks are the same.

Which of the following minerals can scratch Fluorite but be scratched by Feldspar? Quartz Apatite Corundum Fluorite

At which plate boundary does new crust form? Transform Convergent Divergent Continental Crust

The boundary between the Pacific Plate and the Australian plate is a transform plate boundary. What event is most likely to occur at this boundary? Mountain formation Earthquakes Volcanic eruptions Hurricanes

What motion is present at a convergent plate boundary? Two plates moving away from each other. Two plates moving toward each other. Two plates sliding past each other. Nothing happens at a divergent plate boundary.

Which of the following geological events is most likely to occur at a convergent plate boundary where two continental plates collide? Mountain ridges Tsunami Trench Hurricane

Which plate boundary represents a divergent plate boundary?

The weathering of existing rock is the first step in the formation of this type of rock. Sedimentary

Cooled lava helps create this type of rock. Igneous

Minerals that are deposited over long periods of time help create this type of rock Sedimentary

This rock is created from already existing rock. Metamorphic

Minerals from weathering and erosion play a role in the creation of this type of rock. Sedimentary

This type of rock could be found on the slopes of an active volcano or previously active volcano. Igneous

The name of this rock indicates that it has gone through a transformation or change. Metamorphic

This type of rock forms over a very long period of time. Sedimentary

This type of rock starts off as a liquid and as it cools, it becomes a solid. Igneous

This type of rock undergoes a lot heat and pressure in order to form. Metamorphic
