Used this activity? Share your experiences and modifications
Students are provided with data on topography, bathymetry, locations of earthquakes and volcanoes and earthquake focal depths in Google Earth. They are asked to plot a cross-section of topography/bathymetry and earthquake focal depths in OneNote and determine the type of plate boundary.
Introductory physical and historical geology courses for majors and non-majors. Integrates geophysics into a core course in geology Designed for an introductory geology course
Skills and concepts that students must have mastered
Plate tectonic boundaries and the features associated with them (topography, bathymetry, earthquake focal depths, and volcanoes)
How the activity is situated in the course
This is a stand alone laboratory exercise in our physical and historical geology laboratory courses
Content/concepts goals for this activity
Interpret the type of plate boundary from associated features (topography/bathymetry, earthquakes and volcanoes)
Higher order thinking skills goals for this activity
This exercise allows students to interpret real data. It allows them to see the connection between processes occurring at plate boundaries and the features observed at those boundaries (i.e., only deep earthquakes at subduction zones).
Other skills goals for this activity
Searching the WWW and working in groups
Description of the activity/assignment
Students in groups of two are giving access to the Smith and Sandwell topography/bathymetry data and USGS data on earthquakes/volcanoes locations through Google Earth. They are then asked to create a cross-section of topography/bathymetry and earthquake focal depths perpendicular to the plate boundary using OneNote. They then interpret the type of plate boundary. This activity gives students practice in interpreting data, analyzing uncertainty and error in data, and peer teaching. Uses online and/or real-time data, has minimal/no quantitative component.
This activity is a variation on an original activity, Discovering Plate Boundaries developed by Dale Sawyer at Rice University.
Determining whether students have met the goals
Students turn in a digital report showing their OneNote cross-sections and their interpretation. Students also take a short pre- and post-test to see if they have learned basic concepts about plate tectonics.
