Unit 07 Test Review
Section I. Scientists of Plate Tectonics
1. _______________________ is credited with first proposing Plate Tectonics
Theory, and thought that South America and Africa looked like they fit
together like puzzle pieces.
a. Abraham Ortelius
b. Alfred Wegner
c. Harry Hess
d. Arthur Holmes
2. _______________________ found a mid-ocean ridge in the middle of every
ocean, and proposed sea-floor spreading.
a. Abraham Ortelius
b. Alfred Wegner
c. Harry Hess
d. Arthur Holmes
3. _______________________ thought America, Eurasia, and Africa were
once joined and were separated by floods and earthquakes.
a. Abraham Ortelius
b. Alfred Wegner
c. Harry Hess
d. Arthur Holmes
4. _______________________ proposed that convection currents deep in the
Earth drive the movement of tectonic plates.
a. Abraham Ortelius
b. Alfred Wegner
c. Harry Hess
d. Arthur Holmes
5. Scientists believe that the convections currents driving tectonic plate
movement occurs in the ________________.
a. Inner core
b. Outer core
c. Lithosphere
d. Asthenosphere
6. What would be the best possible explanation for fossils of land-dwelling
organisms found on the east coast of South America and the west coast of
Africa?
There was a time in Earth’s history, when the Atlantic Ocean did not exist, and
the continents of Africa and South America were joined together in a
supercontinent. The fossils may be from an organism that lived in the area
during that time.
Section II. Plate Boundaries and Landforms
1. Complete the following table, using the following terms: Ring of Fire, fault
line, divergent, subduction zone, San Andreas Fault, trench, mid-ocean
ridge, transform, volcanic island, mountain, rift valley, convergent, MidAtlantic Ridge, Himalayan Mountains, earthquakes

San Andreas Fault
2. Where would you be most likely to find the MOST recently formed crust?
a. Transform boundaries
b. Subduction zones
c. Divergent boundaries – new crust is formed when the magma rises
as lava through the opening formed by the plates moving apart, and
cools.
d. Convergent boundaries
3. Label the following areas in the diagram below:
a. Young ocean floor
b. Old ocean floor
c. Convergent plate boundary
d. Divergent plate boundary
e. Continental crust
f. Subduction zone
g. Volcanic island

Section III. Topographic Maps
1. Which side of the hill shown above is steeper?
a. North side – contour lines close together indicate steep areas
b. East side
2. If a delta forms on the topographic map that
includes the section shown, in which direction would
you expect the delta to form?
a. To the left
b. To the right
c. To the top – “V” shape points upstream, deltas form
far downstream at the mouth of rivers.
d. To the bottom
3. Which of the following shows the most likely progression from river valley
to canyon?
Now
Future Canyon
a.
The sharper “V” shape indicates the steep sides of the canyon, and the V’s should
point the same direction as the earlier map.
b.
c.
4. A volcano erupts in area that was previously flat. Eventually it goes
dormant, and then is weathered. Put the series of topographic map models
below in the correct order to show the appearance, growth, and
weathering of the mountain.

1-no mountain, flat, 2-small peak, 3- growing peak, 4- highest peak growth, 5-top
of mountain worn down to broad shallow hill, 6-mountain completely weathered
5. A model of the process shown above is created, using a pipe that pumps
mud up through a hole in a flat board, and a ruler that is used to scrape
away the mud to represent weathering. What are some advantages and
limitations of this model? Answers will vary, but should show
understanding of models, the processes of mountain formation and
weathering, and topographic maps.
