The massive slabs of slowly-moving rock just under Earth's surface — known as tectonic plates — may drive bursts of marine biodiversity every 36 million years, a new study finds. As tectonic plates ...
New Haven, Conn. — Earth’s Ediacaran Period, roughly 630 to 540 million years ago, has always been something of a magnetic minefield for scientists. During earlier and later time periods, tectonic ...

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 ...
The Earth with the upper mantle revealed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock in a key region just below the tectonic ...
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 ...
