Plate Tectonics as Expressed in Geological Landforms and Events part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Jeff Ryan, University of South Florida-St. Petersburg
This activity seeks to have students analyze global data sets on earthquake and volcano distributions toward identifying major plate boundary types in different regions on the Earth. A secondary objective is to familiarize students with two publicly available resources for viewing and manipulating geologically-relevant geospatial data: Google Earth(TM) and GeoMapApp.

What Goes into Making Volcanic Arc Magmas, and How Do We Know It? part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Jeff Ryan, University of South Florida-St. Petersburg
This activity is a directed reading exercise focused on papers that have been key to our understanding of the major source contributors to subduction zone volcanic rocks.

A Geologic Safari of the East African Rift and the Newark Basin: Why these areas are more alike than you know part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Margaret Benoit, The College of New Jersey
This activity explores the similarity and differences between the Newark Rift Basin and East African Rift.

Serpentinite in Subduction Zones: How do we find it, and how common is it? part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Jeff Ryan, University of South Florida-St. Petersburg
A mineralogical, petrological, and geophysical exploration of the role of serpentinite in subduction zones, as highlighted in the two NSF-MARGINS Subduction Factory focus sites.

Using geochemical proxies to trace sediment sources part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Karin A. Block, CUNY City College; Annika Johansson, Columbia University in the City of New York
This lecture segments can be used in a mid- to upper-level course to introduce geochemical proxies commonly applied to weathering and sedimentation.

How Slab Dip Affects the Location of Volcanoes part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Erin Beutel, College of Charleston
Students will plot the locations of earthquakes on the top of subducting slabs to determine slab dip and will then develop hypotheses regarding the relationship between slab dip, the depth of the slab, and volcanic activity on the surface.
