Review for Test 5
Tectonic Plate Movement
Introduction to Geology
Relative DatingUnconformities
Fossils
1Name two processes that contribute to the
creation of the driving force behind the movement of tectonic plates.
the Earth’s heatsea floor spreading at mid-oceanic ridges
2What energy source is thought to drive the
lateral motions of Earth's lithospheric plates?
export of heat from deep in the mantle to the top of the asthenosphere
3List three pieces of evidence that support the
theory of plate tectonics.
ocean floor drillinghot spots
paleomagnetism
4Cooler, older oceanic lithosphere sinks into the
mantle at ________.
subduction zones along convergent plate boundaries
5When Earth’s plates move, they cause a deformation in the
Earth’s crust. When deformation occurs at a point on Earth’s surface, the point’s position changes. This position change
can be measured using high-precision _______________________.
GPS instruments
6Name two major divergent plate
boundary zones.
sea-floor spreading at the Mid-Atlantic
Ridgesea-floor spreading
at the Eastern Pacific Ridge
7Several models for plate movement
have been proposed. The picture below
illustrates which model?
the Slab - Pull & Ridge - Push
Model
8The drawing at right is a guess
as to the positions of the
continents:250 million years in the
future
9Catastrophists believed that Earth’s
landscapes had been developed primarily by great catastrophes. James Ussher, in the mid-1600s, concluded that the Earth
was created about:6 000 years ago
10James Hutton’s Theory of the Earth put forth a
fundamental principle of geology called “uniformitarianism.” This principle states that:
the physical, chemical, and biological laws that operate today have also operated in
the geologic past.
11Relative dating means placing rocks in their proper sequence of formation.
This technique:tells us only that events took place
one after the other.
12In the picture to
the right, the column that is
labeled “Younger” and “Older” describes:
relative dating.
13According to the Law of Superposition, put the
layers in the correct order from oldest to youngest.
Supai GroupHermit Shale
Coconino SandstoneToroweap Formation
Kaibab Limestone
14The Law of Superposition states that: in an undeformed sequence of
sedimentary rocks, each bed is older than the one above it and younger
than the one below.
15If you apply the Principle of Original Horizontality
to this picture of the Grand Canyon, what statement could you make that would be
correct?
The layers of rock have not been deformed
since they were deposited.
16The rock layers is this picture are folded at a steep angle, therefore:
they must have been moved into that
position by crustal disturbances
sometime after their deposition.
17We know that Dike A
is younger than any of the rock layers
because of:
the Principle of Cross - Cutting Relationships
18The small inclusions in the intrusive igneous rock layer prove that:
the intrusive igneous rock layer is
younger than the layer above it in
Picture A.
19An unconformity represents a long period during which deposition ceased, erosion
removed previously formed rocks, and then deposition resumed. In other words, it’s a
break in the rock record. Which of the following is not an example of an
unconformity?
[Know the three types of unconformities]
20The unconformity in this picture can
be classified as:a disconformity.
21The unconformity in this picture can
be classified as:a nonconformity
22, 23, 24The point labeled A represents a(n):
nonconformityThe point labeled B represents a(n):
angular unconformity
The point labeled C represents a(n):
disconformity
25List all features in this picture
in order from oldest
to youngest.

26This picture
best illustrates
a(n):disconformity
27Fossils are important inclusions in sediment and sedimentary rocks.
Fossils can be defined as: the remains or traces of prehistoric
life.
28The study of fossils is called
_______________.
paleontology
29The fossils in the picture could best be
described as:unmodified fossils
30Which of the following fossils would
yield the greatest amount of information about the ancient
organism?
31The fossil in this picture is most
likely:
petrified
32This picture shows a single fossil that
has been:cast in a mold
33These three fossils are all considered
to be:impression fossils
34List four example of indirect fossil
evidence.tracks

35What’s does this
picture show?
a coprolite
