  1. GEOL 108 - Crises of a PlanetLab 1 - Plate Tectonics • Sept. 3 - 7, 2012 Department of Earth Sciences

  2. ABOUT ME • Name: Benjamin Gross • Website: http://dornsife.usc.edu/mbg • Phone: 213-740-6743 • Email: martinbg@usc.edu • Office hours (ZHS 300): 12:30-2:30, by appointment ABOUT ME | 2 Department of Earth Sciences

  3. SYLLABUS • Available on Blackboard • Grading • Lab is worth 25% of your overall course grade • 11 labs - lowest x 5 points each = 50 pts max • 11 quizzes - lowest x 10 points each = 100 pts max • Which means quizzes are worth 2/3 of the lab and exercises are 1/3…. or quizzes are worth 17% of your overall grade and exercises 8%. SYLLABUS | 3 Department of Earth Sciences

  4. LAB PREP • Lab exercises available on Blackboard • Print it out, read it, and bring it with you • If you neglect to bring it you will lose 2 points • Note: you are welcome to work with a partner on the exercises but all answers must be your own. Simply copying your partner’s work will be considered cheating. • Bring pencil, calculator, and your printed lab exercise every week SYLLABUS | 4 Department of Earth Sciences

  5. LAB ATTENDANCE • Attendance in your assigned section is mandatory • Email me ASAP if you must miss a lab so we can place you in an alternate section • Legit excuses include serious illness or official university event and require a note • Poor excuses include non-required events, volunteer work, or sleeping in • Unexcused absence will result in a grade of 0 for both the exercise and quiz SYLLABUS | 5 Department of Earth Sciences

  6. LAB EXERCISES • All exercises must be completed during a scheduled lab period • Graded on effort and completion • Show your completed lab to me, I will briefly review it, and return it • Use your lab to study for next week’s quiz SYLLABUS | 6 Department of Earth Sciences

  7. LAB QUIZZES • Quizzes will cover material from the previous week • Begin promptly at the start of class • If you are late and miss the quiz you get a 0 • Expect quizzes to take 10-15 minutes • Combination of formats, but primarily short answer SYLLABUS | 7 Department of Earth Sciences

  8. TERM PAPER • 3 pages of text, double spaced, 11 or 12 point font • Topic is “science behind, and/or the political and social implications and impacts of a current natural disaster” • Due Nov. 27th • Details will be forthcoming SYLLABUS | 8 Department of Earth Sciences

  9. LAB ETIQUETTE • No food or drink in lab • Leave the room if you must use your phone • During a quiz, phone ≠ calculator • Be nice • Pretend to love rocks SYLLABUS | 9 Department of Earth Sciences

  10. LAB 1 - TECTONICS - KEY CONCEPTS • Types of plate boundaries and their locations • Hot spot volcanism: definition and direction of plate movement • Methods of determining plate velocity PLATE TECTONICS | 10 Department of Earth Sciences

  11. PLATE TECTONICS • Movement of lithospheric plates over the asthenosphere. • Plates make contact at plate boundaries • Divergent, convergent, or transform boundary • Active vs. passive continental margin PLATE TECTONICS | 11 Department of Earth Sciences

  12. SUPERCONTINENT FORMATION • Plates move over time, occasionally forming supercontinents http://www.ucmp.berkeley.edu/geology/anim1.html PLATE TECTONICS | 12 Department of Earth Sciences

  13. PLATE MOVEMENT BY GPS PLATE TECTONICS | 13 Department of Earth Sciences

  14. ESTIMATING PLATE MOTION • Estimating sea-floor spreading rates (v=distance/time) • Distance: measured between edges of continents • Time: Age of oceanic crust closest to continent PLATE TECTONICS | 14 Department of Earth Sciences

  15. HOT SPOT VOLCANISM • Volcanic islands form over hot spots • Hot spots do not move, the plate moves above it • Use the distance between islands and difference in rock ages to calculate plate speed For ananimation of hot spot volcanismgo to http://www.wwnorton.com/college/geo/animations/hot_spot_volcanoes.htm PLATE TECTONICS | 15 Department of Earth Sciences
