Are You in a Hotspot? part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This activity is a PowerPoint module designed to help students differentiate hotspot island chains from volcanic island arc systems. The focus sights for this activity are the Society Island hotspot chain and the Caribbean island arc system. Using map images, students are asked to describe and differentiate the topography and geologic features of the two tectonic settings. Vertical exaggeration and topographic profiles are introduced for each site. Students compare the difference in volcanism and seismicity of the two locations. This activity can be used as a lecture enhancement or as a homework or lab exercise.
