The Caribbean plate is merging with which other plate to form
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


the Caribbean Islands? - CORRECT ANSWERS ✔✔the North
|\ |\ |\ |\ |\ |\ |\ |\


American Plate |\




Summarizes the plate tectonic theory - CORRECT ANSWERS |\ |\ |\ |\ |\ |\ |\ |\


✔✔Earth's crust is divided into moving pieces that collide with
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


each other, creating mountain ranges, ocean ridges, and ocean
|\ |\ |\ |\ |\ |\ |\ |\ |\


trenches.


How do the magnetic patterns on the seafloor support the theory
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


of tectonic plates? - CORRECT ANSWERS ✔✔The magnetic
|\ |\ |\ |\ |\ |\ |\ |\ |\


patterns on each side of the ocean ridge are symmetrical, which
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


proves that the seafloor is spreading.
|\ |\ |\ |\ |\




What happens at a divergent plate boundary? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\


ANSWERS ✔✔The plates separate from each other creating new
|\ |\ |\ |\ |\ |\ |\ |\ |\


crust in the process. |\ |\ |\




Why are mountain ranges created where two continental plates
|\ |\ |\ |\ |\ |\ |\ |\ |\


converge? - CORRECT ANSWERS ✔✔Neither plate is subducted;
|\ |\ |\ |\ |\ |\ |\ |\


instead, both are lifted up forming a mountain range.
|\ |\ |\ |\ |\ |\ |\ |\




Besides the discovery of coal in Greenland, what other evidence
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


did Alfred Wegener have to prove his continental drift theory? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\

,CORRECT ANSWERS ✔✔similar fossil records on different
|\ |\ |\ |\ |\ |\ |\


continents


Why does the ocean plate always subduct when it converges with
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


a continent plate? - CORRECT ANSWERS ✔✔because the ocean
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


crust is heavier than continent crust
|\ |\ |\ |\ |\




When an ocean plate and a continent plate converge, which plate
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


subducts? - CORRECT ANSWERS ✔✔the ocean plate
|\ |\ |\ |\ |\ |\ |\




Which type of plate boundary forms new crust? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


ANSWERS ✔✔divergent boundary |\ |\




Upon which layer of the earth do the plates rest and move? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


CORRECT ANSWERS ✔✔asthenosphere |\ |\




According to Alfred Wegener's theory of continental drift, how
|\ |\ |\ |\ |\ |\ |\ |\ |\


were all of the continents originally arranged? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\


ANSWERS ✔✔All continents were part of a large mass of land he
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


called Pangaea. |\




How would you explain the formation of the Hawaiian Islands in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


the middle of the Pacific Plate? - CORRECT ANSWERS ✔✔The
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


Hawaiian Islands are the tops of volcanic mountains formed by
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


hot spots under the Pacific plate; as the plate moves, the hot
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


spots create new islands.|\ |\ |\

, What geologic feature is created when an ocean plate converges
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


with another ocean plate or a continent plate? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


ANSWERS ✔✔trench |\




What type of plate boundaries creates continental mountain
|\ |\ |\ |\ |\ |\ |\ |\


ranges? - CORRECT ANSWERS ✔✔continent-continent convergent
|\ |\ |\ |\ |\


boundary
|\




Why didn't scientists believe Alfred Wegener's theory of
|\ |\ |\ |\ |\ |\ |\ |\


continental drift? - CORRECT ANSWERS ✔✔Wegener had no |\ |\ |\ |\ |\ |\ |\ |\


explanation for what made the continents drift |\ |\ |\ |\ |\ |\




Explain the formation of the Japanese Islands - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\


ANSWERS ✔✔The islands are the result of a convergent boundary
|\ |\ |\ |\ |\ |\ |\ |\ |\


between the Pacific and the Eurasian Plates.
|\ |\ |\ |\ |\ |\ |\




In which direction is the continent of North America moving? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


CORRECT ANSWERS ✔✔toward the Pacific Ocean |\ |\ |\ |\ |\




Which mountain range is being created by the convergence of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


the Nazca and South American plate? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\


✔✔Andes


The North American and Eurasian plates are diverging. What
|\ |\ |\ |\ |\ |\ |\ |\ |\


physical evidence proves this? - CORRECT ANSWERS ✔✔the mid-
|\ |\ |\ |\ |\ |\ |\ |\


Atlantic ridge |\
