- 8. Multiple ChoiceWhich statement about Pangaea is TRUE? (HINT: landmass created from continents being joined together)Pangaea was made of oceanic crust only.Pangaea was made of all the Earth’s tectonic plates.Pangaea contained continental crust only.Pangaea contained both continental and oceanic crust.
- 9. Multiple ChoiceWhat have scientists used to gain information about Earth’s interior?satellite images from GPSseismic waves from earthquakesfossil evidence in the fossil recordlava pillows found at the mid-ocean ridge
- 10. Multiple ChoiceWhat landform is most likely to form when two continental plates collide?a rift valleya deep ocean trencha non-volcanic mountain rangethe mid-ocean ridge
- 11. Multiple ChoiceName the layers of the Earth from hottest to coolest.crust, inner core, outer core, mantleinner core, outer core, mantle, crustinner core, mantle, crust, outer corecrust, mantle, outer core, inner core
- 12. Multiple ChoiceWhich is an accurate description of Earth’s inner core?a dense ball of solid metala layer of molten rocka fluid sphere of liquid metala thin layer of solid rock
- 13. Multiple ChoiceWhat stress force creates a divergent boundary?deformationcompressionshearingtension
- 14. Multiple ChoiceWhen heat is transferred through a fluid (liquid or gas), __ occurs.convectionconductionsubductionradiation
- 15. Multiple Choice
In the picture below, the ocean floor is sinking through a deep ocean trench and back into the mantle. What is this process called?convectionsea-floor spreadingdeconstructionsubduction - 16. Multiple ChoiceWhat is the main type of rock that makes up the oceanic crust?obsidiangranitebasaltlimestone
- 17. Multiple ChoiceWhat happens between oceanic crust and continental crust at a subduction zone?the less dense oceanic crust rises above the more dense continental crustthe equally dense oceanic and continental crusts collide and form mountainsthe equally dense oceanic and continental crusts both sink and form magmathe more dense oceanic crust sinks under the less dense continental crust
- 18. Multiple ChoiceMost geologists believe that the movement of the Earth’s plates is caused by __ in the __.gravity, mantlesubduction, deep ocean trenchesconvection currents, asthenospheremagnetic field, inner core
- 19. Multiple ChoiceWhat theory states that lithospheric plates are in constant slow motion driven by convection currents in the asthenosphere?continental driftplate tectonicssea-floor spreadinglaw of superposition
- 20. Multiple ChoiceWhat type of stress causes plates to converge (collide)?shearingtensioncompression
- 21. Multiple ChoiceWhat type of boundary exists between the North American Plate and the Pacific Plate?transform boundaryconvergent boundarydivergent boundary
- 22. Multiple ChoiceWhere is new crust being added in this diagram?ABC
- 23. Multiple ChoiceWhere is older crust being destroyed in this diagram?ABC
- 24. Multiple ChoiceWhy was Wegener’s theory of continental drift originally rejected by scientists?He used too many pieces of evidence.He could not explain how the continents moved.He was a meteorologist and not a real geologist.He was only interested reconstructing Pangaea.
- 25. Multiple ChoiceWhere do faults normally occur?at plate boundariesat divisions between Earth's layersalong the equatorin the arctic
- 26. Multiple ChoiceWhere are mountain chains (that are NON-VOLCANIC) most likely to occur?in the middle of an oceanic platebetween an oceanic and continental platebetween two colliding oceanic platesbetween two colliding continental plates
- 27. Multiple ChoiceWhy is the inner core a solid, even though it has temperatures hot enough to melt it?Earth’s magnetic field keeps it solid.The pressure from the layers above it keeps it solid.The outer core keeps the inner core cool.The presence of iron and nickel prevent it from melting.
- 28. Multiple ChoiceHow can geologists tell if a volcanic is likely to erupt?Many small earthquakes will be detected in the area near the volcano.Birds will begin to fly toward the opening of the volcano.People living near the volcano will begin to grow sick.The area near the volcano will receive heavy rain for a week before it erupts.

- 32. Multiple ChoiceWhere / how did the Hawaiian Islands form?encircling the entire Ring of Firethrough subduction at a plate boundaryfrom the Pacific Plate drifting over a hot spotby Pangaea breaking apart
