Fragment of lost tectonic plate discovered where San Andreas and Cascadia faults meet
A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating ...
Seismic tremors reveal a shallow fragment of ancient tectonic plate beneath Northern California, helping explain damaging ...
Earth’s crust may have gone on the move roughly 3.8 billion years ago. “Earth is actually quite distinct to other planets, in that it has plate tectonics,” says study coauthor Nadja Drabon, a ...
Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains ...
When you buy through links on our articles, Future and its syndication partners may earn a commission. Plate tectonics may have played a larger role in the evolution of life on Earth than we ...
Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...
Plate tectonics in the Pacific and Atlantic during the Cretaceous period shaped the Caribbean region
The concurrent subduction of the Pacific and Atlantic plates resulted in the formation of a mantle plum and the ascent of magma. Credit: Nicolas Riel Earthquakes and volcanism occur as a result of ...
A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published in the open access journal AGU ...

How the tectonic plates were formed
Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...
Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods ...
Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...
A Brown University study provides new evidence that the icy shell of Jupiter’s moon Europa may have plate tectonics similar to those on Earth. The presence of plate tectonic activity could have ...
