  1. MondayDecember 10, 2012 (Discussion and Worksheet – Mountain Building)

  2. The Launch Pad Monday, 12/10/12 Which of the following energy sources is thought to drive the lateral motions of Earth's lithospheric plates? gravitational attractive forces of the Sun and Moon electrical and magnetic fields localized in the inner core export of heat from deep in the mantle to the top of the asthenosphere swirling movements of the molten iron particles in the outer core

  3. Announcements Happy Make Your List for Santa Day!

  4. Announcements Our next Quiz will be on Wednesday! I will be available after school today until 4:45.

  5. Recent Events in Science Hypergiant Star Amazes for 30 Years A European research team has published the results of a 30-year study of an extraordinary hypergiant star. They have found that the surface temperature of the super-luminous star HR 8752 increased by about 3000 degrees in less than three decades, while it went through an extremely rare stage called the 'Yellow Evolutionary Void'. The discovery marks an important step closer to unravelling the evolution of the most massive stars. Read All About It! www.sciencedaily.com/releases/2012/12/121209152537.htm

  6. Convergent and Divergent Plate Boundaries

  7. Models of Mantle – Plate Convection Mantle plumes extend upward from the mantle - core boundary and cause convection within the mantle. Layering at 660 Kilometers

  8. Models of Mantle – Plate Convection Mantle plumes extend upward from the mantle - core boundary and cause convection within the mantle. Whole - Mantle Convection

  9. Directions and Rates of Plate Motions Directions and rates of plate motion in centimeters per year

  10. Plate Tectonics Into the Future Scientists have extrapolated present-day plate motions into the future some 50 million years. Areas west of the San Andreas Fault will slide northward past the North American plate. Africa collides with Eurasia, closing the Mediterranean and initiating mountain building. Australia and new Guinea are on a collision course with Asia.
