These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found ...

Research suggests that an ancient shoreline helped to sculpt the drop between Mars' southern and northern hemispheres.

Over 25 years ago, researchers discovered that some of these deep Earth reverberations pointed to the existence of two ...

Deeply hidden in Earth's mantle there are two huge 'islands' with the size of a continent. New research shows that these regions are not only hotter than the surrounding graveyard of cold sunken ...

Tectonic plates interact at their boundaries in three primary ways: they move apart, collide, or slide past one another. These interactions produce geological activity, including earthquakes and ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...
