Scientists now understand why seismic waves speed up near Earth's core. Extreme pressure and temperature cause solid mantle rock to flow slowly, aligning mineral crystals. This anisotropic structure ...

SANTA CRUZ, CA–For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps ...

If tectonic plate collisions cause volcanic eruptions, as every fifth grader knows, why do some volcanoes erupt far from a plate boundary? A study in Nature suggests that volcanoes and mountains in ...

Using an anvil made of diamond, researchers discover an secret of Earth's lower mantle. For decades, researchers have studied the interior of the Earth using seismic waves from earthquakes. Now a ...

Two massive blob-like structures deep in Earth’s mantle are revealing a bigger picture about geological phenomena like volcanoes and plate tectonics. One blob lies deep beneath the African continent, ...
