Summary:
Strange things happen in the lower reaches of our planet's mantle, that plastic-like layer between Earth's crust and core that flows under pressure, lifting or lowering features on the surface. Geologists have been intrigued by observations that some seismic waves travel faster than others in particular patches of the lowermost mantle, but they haven't known exactly why that happens. New work by researchers at the University of Michigan and Yale University, published in the March 21 issue of Nature, helps explain the phenomenon and offers new insights into Earth's inner workings.
