Plate Tectonics Quiz Review
What is the name of the
SUPERCONTINENT that was once
one land mass?
Pangaea
Wegener proposed a THEORY
about the continents. He said they
have been moving around for
millions of years.
What did he call this THEORY?
The theory of
Continental
Drift
Untold tragedies of Continental Drift. .
Name the 3 types of heat transfer.

makes the convection currents
move.
A.
B.
C.
D.
sun
core
geothermal activity
Earth’s magnetic field
B. core

• Last summer Beth and her family took a long
cruise. The ship left a port in Argentina (on the
southeastern coast of South America),
traveled just north of Antarctica, then
travelled around southern Australia and
docked in Sydney on the eastern coast of
Australia, over which oceans did it sail?
Atlantic, Southern & Pacific
If a cruise ship leaves a port in California (west
coast of North America) traveling toward
Japan, which ocean is it sailing?
A.
B.
C.
D.
Atlantic
Indian
Arctic
Pacific
• D. Pacific
• Why does mantle rock begin to sink back
towards the lower mantle from the area
closest to the crust?
A. The mantle rock is floating.
B. The mantle rock is cooled near the crust,
becoming more dense.
C. The mantle rock is warmed near the crust,
becoming less dense.
D. The mantle rock does not change near the
crust.
• B. The mantle rock is cooled near the crust,
becoming more dense.
• Wegener used evidence to explain plate
movement. Which of the following was
evidence used in his research?
A. Land features
B. Fossil evidence
C. Climate evidence
D. All of the above
• D. All of the above
• Heat transfers by movement of currents in
liquids and gasses. This is caused by
differences in temperature and density. An
example of this type of heat transfer occurs
when mantle rock moves from near the core,
towards the crust, and back again.
A. Radiation
B. Conduction
C. Convection
D. Compaction
• C. Convection
New ocean floor is added when
plates move ____.
a. together
b. sideways
c. apart
d. parallel
• C. apart
Wegener believed that the continents moved
because of evidence he found which showed
mountain ranges and coal fields matching up on
widely separated continents. Wegener’s use of
this evidence is an example of ____.
a. a prediction
b. a theory
c. an inference
d. a controlled experiment
C. inference
• Harry Hess was an American geologist who
found evidence to support Wegener’s theory.
His research showed that new rock formed on
the ocean floor at the mid-ocean ridge while
older rock was moved farther from this crack
in the oceanic crust. What was this process
called?
A. Continental drift
B. Sea-floor spreading
C. Law of superposition
D. Law of supervision
• B. Sea-floor spreading
