The plate tectonics that determine the shape of our continents may have originated from a huge impact billions of years ago. This huge collision with the Earth, thought to have occurred around 4.5 ...

A new study suggests that tiny, mineral grains — squeezed and mixed over millions of years — set in motion the chain of events that plunge massive tectonic plates deep into the Earth’s interior. The ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...

No one is at their best when they are dehydrated and that goes for tectonic plates too. Researchers using a thermomechanical model of the Alaska subduction zone indicates that plate dehydration is at ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Despite being our closest planetary neighbor, Venus is a pretty ...

Scientists have uncovered one of the most exciting geological discoveries of the decade – the long-lost Pontus tectonic plate. This ancient “mega plate,” which once spanned an astonishing 15 million ...

A peek into the curious geology of the Pacific Northwest helps tease apart what may happen when the last bits of an oceanic plate get swallowed up. Scientists on board the R/V Thomas G. Thompson ...

A new paper has revealed that tectonic activity on this planet—a unique feature in the solar system—could have been spurred by a stream of asteroid impacts. Previously, computer models have shown that ...

A tectonic plate "lost" for 60 million years under the Pacific Ocean has been reconstructed by scientists at the University of Houston. Known as Resurrection, the plate has been a controversial topic ...
