Our class investigated the pattern of volcanoes along the plate boundaries. We wanted to see if certain types of volcanoes were associated with certain types of plate boundaries. Teams investigated different areas of the world. Using AEJEE and Google Earth, we determined that convergent plate boundaries have composite volcanoes and divergent plate boundaries have shield volcanoes and sea floor pillow lavas.

6. TEAM WORK
• Randomly teams of three students will be given a
specific area of the world that has a lot of
volcanic activity.
• It is the team’s responsibility to do the following:
– ‘code’ the volcanoes and screen capture their area
– Using Google Earth, map out the boundary and screen
capture their area
– Determine the type of plate boundary
– Determine the main type of volcanic activity at this
location

7. PRESENTATION
• Create powerpoint slides that show the screen
capture from AEJEE and Google Earth
• Include a graphic that illustrates an example of
this type of volcano from this area
• As a class, create one sentence that shows the
relationship between that specific plate
boundary and the main type of volcanic
eruption

67. CLASS FINDINGS
• DIVERGENT PLATE BOUNDARIES are
characterized by pillow lavas and shield
volcanoes. This is because the magma is
coming from the mantle and is low in silica.
This produces short, broad volcanoes with
quiet eruptions.

68. • CONVERGENT BOUNDARIES produce very
explosive volcanic eruptions characterized by
composite volcanoes such as Mt. Fuji and Mt.
St. Helens. These volcanoes are the result of
the subducting plate being melted and coming
back to the surface as a composite volcanic
eruption either in islands or mountains.
