Earth has four primary layers: the crust, mantle, outer core, and inner core. The crust is a thin, solid layer upon which all life resides. Underneath it is the mantle, a hot, dense layer of ...

Researchers are now trying to understand the "innermost inner core" of the Earth by studying how seismic waves travel through ...

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust above it to "drip" and suck down rocks from across the continent.

Beneath the American Midwest, on the continent of North America, the underside of Earth's crust is dripping into the planetary interior. There, blobs of molten rock are coalescing in the upper mantle ...

In a new paper published in Nature today, colleagues and I reveal secrets of Earth’s crust 4.5 billion years ago. In the process, we also provide a new way to approach one of the biggest ...
