10 TS Ivan

11 Example of integration of sciences 1. Biology of Formation 2. Geology of Discovery 3. Engineering of Extraction 4. Technology of Transport 5. Chemistry of Refining 6. Statistics of Supply/Demand 7. Economics of Pricing 8. Technology & Feasibility of Alternatives Petroleum Study

12 TJ Academic Goals Problem solving Academic risk taking Geosystems projects emphasize Students move from unrelated facts to knowledge.

13 Example: A plate tectonics project where a huge data base is available Bottom line: How do you substantiate your findings? What data are associated with a boundary? What data are irrelevant? What data are anomalous?

14 31,419 Earthquakes in 2003

15 Where’s the trench? Multiple Plate Boundary Types Ocean to Ocean? Convergent or transform? Relevant?

16 Transform Plate Boundary Why are those intermediate depth earthquakes there?

17 Geosystems An imaginative & comprehensive course that continually receives praise from professors, graduates, and students alike and students alike Positive UVa review
