GLY1102 | Exam Actual Questions & Verified
Answers | 100% Correct | A Grade – 2026
Using the velocity arrows, which two plates appear to be moving the most?
The Indian-Australian Plate and the Pacific Plate
There is not a legend on this map to tell you which plate boundary type is illustrated by each
symbol (thick white line vs. black line with points). But you can determine which is which by
looking at the plate motions illustrated by the arrows. What kind of boundary exists between
the Indian-Australian and Pacific plates?
convergent
What kind of geologic features would you expect along this boundary from Question #2?
Choose all the answers that make sense for this boundary:
volcanoes
mountains
earthquakes
Use a ruler or piece of scratch paper and the arrow key in the lower left of the map to
estimate the rate of movement for the North American plate as measured by GPS. What is the
rate of movement for North America?
about 2.5 centimeters per year
Use Figure 2 for questions 5 & 6.
Use Figure 2 for questions 5 & 6. Say you were looking for the oldest rocks on the seafloor in
the Atlantic Ocean on the JOIDES Resolution - a scientific research ship that can extract rock
samples from the seafloor. Would you look close to land or far out in the ocean?
close to land
,Say you were looking for oceanic crust that formed in the Cretaceous. You still are on board
the JOIDES Resolution. Which of the following locations would you sail to?
South of the Hawaiian Islands.
The first true dinosaurs appear in the fossil record 200 million years ago, after what major
event?
mass extinction
Find the outlines of modern-day North America and Africa on the globe and find where they
intersect on the supercontinent Pangea during the Early Triassic - 240 million years ago.
Compare that same area in the Late Triassic - 200 million years ago. What new feature
emerges in the Late Triassic?
A rift valley flooded with sea water.
Use the globe to determine approximately when South America and Africa separated into two
different continents.
Between 105 and a 120 million years ago.
Jump to 150 million years ago and look for Florida (Hint: if you are having trouble finding it,
just type a Florida city name into the search bar in the top left corner). Now jump to 105
million years ago and look for it again. It becomes clear why we don't find dinosaurs fossils in
Florida! It's because:
Florida is underwater during this whole time.
The landscapes of modern-day Caracas, Venezuela and Birmingham, Alabama USA don't
appear to have much in common, but geologically speaking they share some history. Use the
city search box to find both cities. Now go back in time to 240 million years or earlier. What
do these locations have in common?
These locations were once part of the same contient range.
,Look at the globe at the 150 and 105 million year mark. How would you describe the change
in sea level between these two points in time?
Sea level was significantly higher during the Cretaceous.
The North and South American continents rifted apart during the Jurassic. They were finally
re-connected by the land that makes up the southern end of Central America around __
million years ago (mya).
0 mya; Yes! It was actually around 4.5 million years ago. Not that long ago in geologic terms!
Which stratigraphic principle tells you the Igneous sill (F) is younger than the Bass Dolomite
(E)?
The principle of cross-cutting relationships.
The wavy black lines marked as S and R on the diagram represent:
Unconformities - times of erosion in the past that took away some of the rock record from what
was then the Earth's surface.
True or false: the rocks in the Precambrian section are in the same orientation they were in
when they first formed.
False
Study this diagram of the Grand Canyon and put the letters corresponding to different
features in age-order using the Principles of Stratigraphy.

Technically, there is one feature in the diagram that could be put in any time after feature E
and not break any rules of stratigraphy. What is it?
The igneous sill, feature F
, Find the Monument headquarters and Independence Monument. Which is located on the
younger rock?
Headquarters
Find location 3 on the map. This is an outcrop of the Jurassic age Kayenta formation (Jk). The
rocks surrounding this location are ____________ than the Jk formation
older
If you were to travel from Location 2 to Location 3 in a straight line, how would you describe
the ages of the rock units you are waking across?
The rocks get progressively older from Location 2 until about the halfway point, then
progressively younger until you reach Location 3. Oldest rocks in the middle of the hike.
All the rocks in this area are sedimentary (with the exception of the Precambrian rocks
marked with an "X") which means they were deposited in flat, roughly horizontal layers.
There is no elevation data displayed on this map, but we can use what we observed in the
previous question and the Stratigraphic Principle of Superposition to get a rough idea of what
kind of elevation change our hike would have. (Hint: Do an image search on the web for
'Colorado National Monument' to see if you are on the right track.)
The elevation of the hike from Location 2 to Location 3 would most likely be:
A hike that starts on a high plateau, goes down into a valley and back up onto another shorter
plateau
This area is well-known for dinosaur fossils, but you can't find them just anywhere - you have
to know where to look. For example: Stegosaurus existed from 164-145 million years ago.
Which number corresponds to the area where you would have the best chance of finding
stegosaurus bones?
