QUIZ Plate Tectonics
NAME__________________________
Use 2-3 complete sentences to answer each part of questions 1, 2 and 4 unless the question asks
for a list. Wherever possible, give specific details, and be sure to tie your thoughts back to the
question. Use a sketch if it helps. Refer to instructor’s directions for completion and submission.
1.
a. Briefly explain using specific detail or examples how the following observations were
used to support Wegener’s hypothesis of continental drift. (choose 3)
fit of the continents
paleoclimate
fossil record
glacial evidence
mountain ranges and rock types
b. What important explanation was missing from Wegener’s hypothesis?
c. Has it since been proven that the continents do indeed drift?
2.
Explain using specific examples. how the theory of plate tectonics is supported by
the following: (choose 2)
magnetic reversals recorded in the ocean crust and/or lava flows
age of ocean crust
apparent polar wandering
occurrence of most earthquakes and volcanoes in specific regions on earth
3.
Briefly explain how the steps of the scientific method were applied in the continental drift
hypothesis and later to develop plate tectonics.
Why is plate tectonics considered the unifying theory of geology?
List 3 geological observations or events that are best explained by the theory of plate
tectonics.
4.
Match the tectonic setting associated with the geographic area or feature by putting the
correct letter in the blank in front of the location. You may refer to maps provided.in class.
A Divergent boundary
B Convergent boundary
C Transform boundary
D Hot Spot (intraplate)
1._____ Mid Atlantic Ridge
6_____ Japan Volcanic Arc
2_____ East African Rift Valley
7_____ Andes Mountains (South America)
3_____ San Andreas Fault (California)
8_____ Cascade Mountains (Washington State)
4_____ Himalayan Mountains
9_____ Yellowstone (Wyoming)
5_____ Hawaii
10_____ Pacific Ridge (breaks that are
perpendicular to the ridge)
5.
Make 5 sketches of plate boundaries. Sketch a divergent boundary, three types of
convergent boundaries, and a transform boundary.
For convergent and divergent, sketch a “side view” and include arrows that show
plate motion. Also label the type of crust involved. For the transform, a simple
sketch in “plan view” – as if you were looking down on the surface from above.
