Lab F
our
teen: Geospatial Technologies
In this activity, you will investigate the various types of plate boundaries using earthquake depth and
location to determine boundary type using geospatial technology. In addition, you will explore the use of
geospatial technologies and how you may apply them to your major.
Materials:
Computer
Objectives:
•
Identify relationships between earthquakes and plate boundaries.
•
Research geospatial technologies applications for your course of study.
•
Identify potential jobs and earning potential.
Part 1: Plate Tectonics and Earthquakes
Have you ever considered the relationship between plate boundaries and earthquake depth and location?
Part 1 of the lab uses geospatial technology to interactively explore this relationship.
Exercise 1

.1:
1.
Click on the map URL:
http://esriurl.com/earthgeoinquiry6
to launch the map.
2.
With the Details pane visible, click the button, Show Contents of Map.
3.
Turn on the layer, Global Quakes Of Large Magnitude 5.8 Or Greater.
Q1: What patterns are visible where quakes occur?
4.
Turn on the layer, Relative Motion At Plate Boundaries. Note that you will not see anything until you
perform the next step.
5.
Press the button, Bookmarks. Select a Bookmark and answer question 2 before selecting another
Bookmark.
Q2a:
Record the plate movement in the table below.
Bookmark
Plate Movement (e.g., colliding,
moving apart, sliding past)
Boundary Type (e.g. convergent,
divergent, transform)
California
South America
Mid Atlantic Ridge
Earthquakes occur where large pieces of the earth’s crust run into, pull away from, or slide against other pieces
of independent crust.

6.
Turn on the layer, Plate Boundaries.
7.
Click the Plate Boundaries layer name so you can see its legend.
8.
Revisit each bookmark and answer Question 3 before selecting another bookmark.
Q
2
b
:
Record the boundary type in the table above.
9.
Turn off the layer, Global Quakes Of Large Magnitude 5.8 Or Greater .
10.
Turn on the layer, South American Quakes.
11.
Hover the mouse over the layer name, South American Quakes.
12.
Click the button, Change Style.
13.
Change the attribute (#1) from Show Location Only to Depth_km. – The new symbology draws dots
larger according to how deep quakes occur.
14.
Click Done to apply these changes.
15.
Using the Bookmark for South America, answer the following questions:
Q3:
Do these earthquakes occur only at the boundary between plates?
Q4: What is happening between these two plates that would create this pattern of earthquake depth?
16.
Complete the following table by also looking at Quake Depth for the California and Mid Atlantic Ridge
layers.
Q5: Complete this chart:
Plate Boundary
Pattern of Quakes compared to
Boundary (e.g. one side only, both
sides, close to boundary)
Pattern of Depth (e.g.,
shallow, gets progressing
deeper, mixed depths)
Convergent
Divergent
Transform
17.
Hover the mouse over the layer name, Plate Boundaries.

18.
Click the button, Change Style.
19.
Change the attribute (#1) from Boundary_Type to Show Location Only.
– The new symbology draws all
plate boundaries as black lines.
20.
Click Done to apply these changes.
21.
Turn on the layer, Caribbean Quakes.
Q6: Based on the table in Question 5, what type of plate boundary occurs here?
