Researchers have discovered that the underside of the North American continent is dripping away in blobs of rock—and that the remnants of a tectonic plate sinking in Earth's mantle may be the reason ...

The Farallon plate and the North American plate once formed a subduction zone along the continent's west coast, with the former sliding beneath the latter and recycling its material into the mantle.

The deep roots of Earth's oldest continents have long been thought to be unshakable. But a new seismic discovery suggests that even these stable landmasses can change. Beneath the center of North ...

A new study details how the North American plate is “dripping” into the mantle due to the continued influence of the Farallon Plate, which has been subducting under the continent for 200 ...
