Plate Tectonics as Expressed in Geological Landforms and Events
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.

Exploring Evidence of Plate Tectonics Using GeoMapApp
Sean Cornell, Shippensburg University of Pennsylvania
This activity requires students to explore a range of datasets that help substantiate Plate Tectonic Theory. Students investigate plate tectonic environments (convergent, divergent, transform boundaries), topography/bathymetry of continents and ocean basins, the distribution and pattern of earthquakes, the distribution of volcanoes, as well as ages of the sea-floor, and more.

From Ocean Topography to Flexural Rigidity
Andrew Newman, Georgia Institute of Technology-Main Campus
Students will use the available bathymetric datasets to test the utility of a flexural rigidity model of oceanic crust.

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

Online Investigation of an Island Arc Volcano: Anatahan, Mariana Arc
Jeff Ryan, University of South Florida-St. Petersburg
This activity is a Web investigation and research exercise starting with the 2003-present Anatahan volcanic eruptions in the Mariana arc, and concluding with a petrologic examination of published Mariana arc lavas data sets.

Serpentinite in Subduction Zones: How do we find it, and how common is it?
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.

What Kind of Continental Margin am I? Active or Passive?
Laura Wetzel, Eckerd College; Cindy Palinkas, University of Maryland-College Park; Karen Bemis, Rutgers University-New Brunswick; John McDaris, Carleton College
Volcanoes, earthquakes, and topography reveal whether a continental margin is active or passive. In this activity, students use the GeoMapApp tool to work with earthquake, volcano, and topographic data to identify ...

Source to Sink Morphology, Sedimentation, and Anthropogenic Impact: Hudson System, New York
Cecilia McHugh, CUNY Brooklyn College
Familiarize students with the morphology of passive continental margins and their associated shelf valleys, submarine canyons and estuaries, and assess the anthropogenic impact.

Volcanoes of Central America
Michael Carr, Rutgers University-New Brunswick
Volcano distribution and tectonics at a convergent margin: Central American volcanoes

Margin Morphology: Does Form Follow Function?
Leslie Sautter, College of Charleston
Students will use GeoMapApp to investigate variations in the geomorphology of continental margins – both Passive and Active – at various sites of the North American and South American continents. They will ...
