Detecting Cascadia's changing shape with GPS | Lessons on Plate Tectonics part of Geodesy:Activities
Research-grade Global Positioning Systems (GPS) allow students to deduce that Earth's crust is changing shape in measurable ways. From data gathered by EarthScope's Plate Boundary Observatory, students discover that the Pacific Northwest of the United States and coastal British Columbia — the Cascadia region - are geologically active: tectonic plates move and collide; they shift and buckle; continental crust deforms; regions warp; rocks crumple, bend, and will break.

Converging Tectonic Plates Demonstration part of Geodesy:Activities
During this demo, participants use springs and a map of the Pacific Northwest with GPS vectors to investigate the stresses and surface expression of subduction zones, specifically the Juan de Fuca plate diving beneath the North American plate.

Getting started with Structure from Motion (SfM) photogrammetry part of Cutting Edge:Enhance Your Teaching:Teaching with Online Field Experiences:Activities
Structure from Motion (SfM) photogrammetry method uses overlapping images to create a 3D point cloud of an object or landscape. It can be applied to everything from fault scarps to landslides to topography. This ...

Igneous Rocks and Triangle Diagrams part of Introductory Courses:Activities
This activity takes place in a laboratory setting and requires ~1.5-2 hours to complete. Students observe igneous rock compositions and plot them on triangle diagrams, normalize rock compositions using a ...

Visualizing Relationships with Data: Exploring plate boundaries with Earthquakes, Volcanoes, and GPS Data in the Western U.S. & Alaska | Lessons on Plate Tectonics part of Geodesy:Activities
Learners use the GPS Velocity Viewer, or the included map packet to visualize relationships between earthquakes, volcanoes, and plate boundaries as a jigsaw activity.

Sedimentation Provenance Problem Set part of Sedimentary Geology:Activities

Measuring the Inclination and Declination of the Earth's magnetic field with a smartphone part of Cutting Edge:Enhance Your Teaching:Teaching with Online Field Experiences:Activities
The poles of the Earth's magnetic field are not precisely aligned with the geographic north and south poles and, in fact, vary continuously. This activity introduces to students the Earth's magnetic ...

Seafloor Spreading: Bathymetry, Anomalies, and Sediments part of Introductory Courses:Activities
This activity takes place in a laboratory setting and requires ~1.5-2 hours to complete. Students study the bathymetry of the South Atlantic, use magnetic reversals to interpret marine magnetic anomalies, and ...

Measuring Ground Motion with GPS: How GPS Works part of Geodesy:Activities
With printouts of typical GPS velocity vectors found near different tectonic boundaries and models of a GPS station, demonstrate how GPS work to measure ground motion.GPS velocity vectors point in the direction that a GPS station moves as the ground it is anchored to moves. The length of a velocity vector corresponds to the rate of motion. GPS velocity vectors thus provide useful information for how Earth's crust deforms in different tectonic settings.
