Map of plate boundaries, selected earthquakes, and GPS velocities relative to NAM08 reference frame (fixed to the stable cratonic interior of North America), produced using UNAVCO's GPS Velocity Viewer.

Note: We will be working primarily with the Lab Manual as we study this topic, but please use the Tarbuck and others Earth eText as a reference resource as you seek to find answers for the study questions that you can't find in the Lab Manual.

1. Read : the study questions for this section, listed at https://croninprojects.org/Vince/Course/PhysGeol/Geo1405-Tectonics-Q2021.html and keep them in mind as you read the following assignments. Most, if not all, of the answers will be in the reading assignments for this topic.
2. Scan : Tarbuck and others, Earth eText, chapter 2 — the whole chimichanga. A reminder about how to get to the eText is provided HERE
   Don't neglect to view all of the AV stuff: videos, animations, tutorials, concept checkers. Do these things in light of the study questions, so that you pick-up some information and know where to look for more information as you work to find the answers to those questions and understand the associated content.
3. View the videos Comments on tectonics, part 1 at https://youtu.be/9RhUB2lvPVQ
   and Comments on tectonics, part 2 at https://youtu.be/40hlD4gVT4c
   My videos reference other videos you should look at, namely...
   • the IRIS video on Earth's internal layers: https://youtu.be/UD7GHzIRI-s
   • the IRIS video What is the Moho? How was it discovered? https://youtu.be/omZj4GboJ00
   • the IRIS video on Plate Boundaries & Tectonic Plates https://youtu.be/Xzpk9110Lyw
   • the National Geographic Society video on plate movement from 200 million years ago to today: https://www.iris.edu/hq/inclass/animation/plate_movement__200_million_years_ago_to_today
   • the IRIS video on hotspot volcanism: https://youtu.be/AhSaE0omw9o
   • the IRIS video about the forces that drive the plates: https://youtu.be/Nf8xvhb1eBE
4. OPTIONAL but Recommended: Take advantage of any of the following videos:
   • 1.5 billion years of Plate Tectonics, by Chris Scotese: https://youtu.be/IlnwyAbczog
   • Plate Tectonics, 540 Ma- Modern World, by Chris Scotese: https://youtu.be/g_iEWvtKcuQ
   • 240 million years ago to 250 million years in the future, by Chris Scotese: https://youtu.be/uLahVJNnoZ4
5. Complete the lab assignment: https://croninprojects.org/Vince/PhysGeoLab/TectonicsLab-F21.html
6. Complete the assigned work in Mastering Geology
   Complete the Dyamic Study Module called Plate Tectonics and HW-ch02 by going to Mastering Geology through the Canvas Learning Management System (LMS). A reminder about how to get to the Mastering Geology assignments is provided HERE
