Luster is the property that is considered metallic or non-metallic.
100
6.10A $100 - Which Earth's layer is the largest, thickest layer?

100
6.10C $100 - What key words tell you we are talking about a sedimentary rock?
Key words for sedimentary rock are weathering, erosion, deposition, compacted, cemented, sediment.
200
6.8D $200 - During which interval is the object moving back towards home?
Between E and F - When the graph is sloping down, the object is moving back towards "home".
200
6.8E $200 - Give one example of when an inclined plane would be useful.
An inclined plane would be useful in... wheelchair ramps, moving van ramps, slides, screws, etc.
200
6.6C $200 - If a mineral sample can be scratched by glass, what do we know about the hardness of the mineral sample according to the Mohs hardness scale (look at the numbers)?
The glass is harder because it is doing the scratching (glass scratches mineral sample) so the mineral's hardness must be less than 5.5.
200
6.10A $200 - Looking at the diagram, which section of Earth is composed primarily of liquid metal?
C - The outer core is the only liquid layer of the Earth.
200
6.10C $200 - According to the rock cycle, when liquid magma cools into a solid, what is formed?
Igneous rock is formed when magma cools into a solid.
300
6.8D $300 - During which interval is the object stopped and staying the same place?
Between B and C, between D and E, between F and G - When the line is flat, the object stopped moving (its distance does not change).
300
6.8E $300 - Which type of pulley will decrease the amount of force?
A movable pulley will decrease the amount of force.
300
6.6C $300 - A mineral sample is scratched by topaz and quartz. It cannot be scratched by apatite and fluorite. According to the Mohs Hardness Scale, what is the mineral sample's hardness?
The mineral sample's hardness must be a 6 (apatite 5, fluorite 4, quartz 7, topaz 8).
300
6.10A $300 - What is the name of the Earth's section that includes the crust and uppermost mantle where tectonic plates are located?
The lithosphere includes the crust and uppermost mantle.
300
6.10C $300 - Two tectonic plates pushing toward each other cause intense heat and pressure in Earth’s crust. What type of rock will crust material be changed into by heat and pressure?
Rocks become metamorphic rocks when changed by heat and pressure.
400
6.8D $400 - Which sections of the graph best matches this description? "A girl is walking from home to the beach. When she got there, she stayed on the beach and built a sandcastle. She got hot from the sun, so she ran to the ice cream shop."
Between A and D - A to B is the girl walked from home to the beach, B to C is when she stopped at the beach to build a sandcastle, and C to D is when she ran to the ice cream shop.
400
6.8E $400 - Looking at the pulleys on your paper, which pulley will decrease the force the most: A, B, or C?
Pulley C will decrease the force the most because it uses multiple pulleys.
400
6.6C $400 - What property of a mineral can be determined just by looking at it?
The mineral's color and luster can be determined just by the looking at it.
400
6.10A $400 - What is the proper name for the section of the mantle that is semi-molten and has plasticity (able to flow)?
The asthenosphere is the section of the mantle that is able to flow due to convection currents.
400
6.10C $400 - Which type of rock can form on the surface of the crust near a volcano?
An igneous rock can form on the surface of the crust near a volcano when lava cools and hardens.
500
6.8D $500 - Which sections of the graph best matches this description? "A turtle was 20 meters from home on a log in a lake. He swam away from the log and reached land. A bird scared him so he hid in his shell. He decided to go back to the log, hang out there for a bit, then swam to a friend's habitat."
Between C and H - C to D is swimming from the log to the land, D to E is hiding in the shell, E to F is going back to the log, F to G is hanging out on the log, G to H is swimming to friend's habitat.
500
6.8E $500 - If you need to lift a heavy object in a small area, would an inclined plane or a pulley be better and why?
The pulley will take up less space in the small area than an inclined plane.
500
6.6C $500 - A student rubs a mineral across a hard surface and a powdery residue is left behind. What property is the student testing?
The powdery residue is the mineral's streak.
500
6.10A $500 - What would be the most accurate description for the lithosphere?
The lithosphere contains the different sections of crust (continental and oceanic) and the uppermost mantle.
500
6.10C $500 - Which type of rock is formed when particles (sediment - sand, fossils, pebbles) are compacted and cemented together?
A sedimentary rock is formed when particles are compacted and cemented together.
