Geophysicists from the University of Maryland made the first analysis of seismic echoes from hundreds of earthquakes at once, unveiling more widespread, heterogenous structures at the core-mantle boundary than previously known. Past studies were limited to single...

Plate tectonics has been on the curriculum for a while now. Most people are fairly familiar with the theory; the Earth's crust - or lithosphere - is broken up into different plates which move around on the very hot, viscous substance beneath.This movement is driven

For years, researchers have debated whether or not the Hawaiian hot spot — the active volcanic region that created the islands — is fueled by a plume of hot magma rising straight up from the Earth's depths. Not so, new research finds. Instead, a giant, d
