6. Recent Events in Science Hypergiant Star Amazes for 30 Years Read All About It! www.sciencedaily.com/releases/201 2/12/121209152537.htm 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.

7. Convergent and Divergent Plate Boundaries

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

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

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

11. 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. Plate Tectonics Into the Future Africa collides with Eurasia, closing the Mediterranean and initiating mountain building. Australia and new Guinea are on a collision course with Asia.
