Overview
In the “On Shaky Ground” unit you have focused your inquiry on comparing divergent,
convergent, and transform boundaries. In this assessment you will use the same skills to
compare and contrast different types of convergent boundaries. For example, are the
earthquake patterns for oceanic-continental convergent boundaries the same as those for
oceanic-oceanic convergent boundaries or for continental-continental convergent
boundaries?
Part A: How do convergent boundaries compare?
A1. What similarities in earthquake patterns might you expect to find between oceaniccontinental, oceanic-oceanic, and continental-continental convergent boundaries? What
are you basing your hypothesis on?
A2. What differences in earthquake patterns might you expect to find between oceaniccontinental, oceanic-oceanic, and continental-continental convergent boundaries? What
are you basing your hypothesis on?

Part B: Analyze Data
Look at the map to answer the following questions.
B
C
A
B1. Next to each picture on the next page summarize the data and describe the patterns of
earthquakes along each boundary.
B2. Describe and label each picture with the type of convergent boundary (continentalcontinental, continental-oceanic, oceanic-oceanic) and the letter it corresponds to with the
map above.

Part C: Conclusions
C1. Compare the magnitude, depth and location of earthquake epicenters along the
convergent boundaries by completing the table below:
Magnitude
(small to medium,
OR medium to,
large)
Depth
(shallow,
Shallow to medium,
OR
Shallow to deep)
Location
(On the boundary.
More on one side of
boundary then the
other, OR
scattered etc.)
Continental-Continental
convergent boundary
Continental- oceanic
convergent boundary
Oceanic- Oceanic
convergent boundary
C2. Draw a sketch of the different convergent boundaries. Draw and label the location
of the earthquakes along the convergent boundaries.

C3. Explain how the process along each type of boundary helps describe the patterns you
see with the data.
C4. Look at the data for location C on the map. Predict the likelihood of big earthquakes
(magnitude greater than 6.5) occurring there within the next 50 years. Explain your
reasoning.
