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

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