- 5. Multiple ChoiceWho is known as the "Father of Continental Drift"?Harry HessAbraham OrteliusAlfred WegnerJohn Tuzo Wilson
- 6. Multiple ChoiceWhat are the deepest places on Earth formed by pushing oceanic crust under continental crust?mid-ocean ridgesrift valleystrenchesmountain ranges
- 7. Multiple ChoiceWhat forms when denser oceanic crust is pushed under less dense oceanic crust?mountainsvolcanic islandsrift valleysmid-ocean ridges
- 8. Multiple ChoiceThis theory states that Earth's plates move on top of the mantle at a slow and constant rate due to convection currentsplate tectonicscontinental driftseafloor spreadingpangaea
- 9. Multiple ChoiceLarge pieces of Earth's lithosphere that move around are called?sectionsplatesland massesfaults
- 10. Multiple ChoiceWhich piece of evidence was not used by Wegener to support his theory of continental drift?South America and Africa coastlinescoal beds in Antarcticaplant and reptile fossilsearthquake patterns
- 11. Multiple ChoiceWhat forms when two oceanic plates diverge?moutainsrift valleymid-ocean ridgedeep-ocean trench
- 12. Multiple ChoiceWhat is associated with transform boundaries?mountainsvolcanoesearthquakesislands
- 13. Multiple ChoiceWhat occurs when two plates come together and the denser one is forced under back into the mantle?reductionconductionsubductionconvection
- 14. Multiple ChoiceA break or crack in the Earth's crust is called a...platefaultfoldcrack
- 15. Multiple ChoiceWhich type of plate boundary would cause folded mountains to form?transformconvergentdivergentsubduction
- 16. Multiple ChoiceWhat are the two types of crust?continental and oceanicocean and basinlower and upperthick and thin
- 17. Multiple ChoiceWhat drives tectonic plate movement?gravitycoriolis effectconvection currentsthe earth's magnetic core
- 18. Multiple ChoiceEarthquakes and volcanoes are most likely found in which locations?at plate boundariesin oceansin the middle of continentsin the middle of plates
- 19. Multiple ChoiceWhen an oceanic plate and a continental plate collide, which one will subduct?oceaniccontinentalneitherboth
- 20. Multiple ChoiceAccording to Wegener's hypothesis of continental drift,Earth's surface is made up of seven major landmassesthe continents DO NOT moveEarth is slowly cooling and shrinkingthe continents were once joined together in a single landmass
- 21. Multiple ChoiceMost geologists rejected Alfred Wegener's idea of continental drift because...it did not agree with their current theoryWegener was interested in what Earth was like millions of years agoWegener used several different types of evidence to support his hypothesisWegener could not identify the force that moved the continents
- 22. Multiple ChoiceWhat were magnetic stripes on the ocean floor used to show?the seafloor was spreading outward from the mid-Atlantic ridgethe seafloor was spreading inward toward the mid-Atlantic ridgethe seafloor was effectively stationarynatural magnetic rocks always form in the mantle of the Earth
- 23. Multiple ChoiceThe youngest rocks on the seafloor are most likely found...closest to a mid-ocean ridgefarthest from a mid-ocean ridgenear the coastlinesclosest to a deep sea trench
- 24. Multiple ChoiceThe Andes Mountains are a volcanic mountain range located on the western coast of South America. The plate boundary located in this region is most likely an area of-subduction because the plates are collidingfolded mountains because the plates are collidingmid-ocean ridges because the plates are pulling apartocean-floor spreading because the plates are spreading apart
