Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

In 2021, geologists animated a video that shows how Earth's tectonic plates moved over the last billion years. The plates move together and apart at the speed of fingernail growth, and the video ...

A study published in the journal Tectonics has provided new insights into the forces that cause tectonic movements in Europe's most seismically active regions. Researchers used advanced satellite data ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. Carole ...

Venus, a scorching wasteland of a planet according to scientists, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. PROVIDENCE, R ...

Results from an expedition to the sea floor near the Hawaiian Islands show evidence that the deep Earth is more unsettled than geologists have long believed. A new University of Rochester study ...

The new research used 4-D geodynamic modeling to predict tectonic movement over hundreds of millions of years. According to Huang, the results indicate it is most likely the Pacific Ocean will close, ...

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 ...

New simulations of the asthenosphere find that convective cycling and pressure-driven flow can sometimes cause Earth's most fluid layer of mantle to move even faster than the tectonic plates that ride ...

There's something weird going on in the Atlantic Ocean. Off the coast of Portugal, a tectonic plate may be peeling apart, with the top layer separating from the bottom, a scientist has proposed. João ...

Scientists have reconstructed a long-lost tectonic plate that may have given rise to an arc of volcanoes in the Pacific Ocean 60 million years ago. The plate, dubbed Resurrection, has long been ...

One would assume the lithosphere would be lower-density than the asthenosphere. As the lithosphere tries diving into the layer below it wouldn't it want to float back to the top? Rather than the ...
