Profiling Earth's Surface using GeoMapApp
In this exercise, students relate large-scale features on Earth's surface to lithospheric plates, the underlying asthenosphere, earthquakes, and volcanoes. After creating a cross section showing elevation using GeoMapApp, students add additional features by hand.

How Slab Dip Affects the Location of Volcanoes
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.

From Ocean Topography to Flexural Rigidity
Students will use the available bathymetric datasets to test the utility of a flexural rigidity model of oceanic crust.

What does "spatial resolution" mean? Some answers using MARGINS data.
The main objective of this presentation is to understand the concept of spatial resolution by looking at the concepts of point, grid and pixel.
