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 ...

THAT AUTUMN, A RESEARCH VESSEL called the Glomar Challenger sailed over the Mid-Atlantic Ridge to drill holes and sample sediment. Fossils within the sediment samples they retrieved gave scientists a ...

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 ...

Scientists warn that the plate beneath Gibraltar arc will begin to shift toward the Atlantic within 20 million years.

A geologic map of the Pilbara Craton in Western Australia. The rocks exposed here range from 2.5 to 3.5 billion years ago, offering a uniquely well-preserved window into Earth's deep past. The authors ...

New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that ...

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 ...

Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. Researchers had previously identified ...

A groundbreaking study has provided new insights into the forces that cause tectonic movements in Europe’s most seismically active regions. Researchers used advanced satellite data to track land ...

The cyclic strengthening and weakening of ocean tides over tens of millions of years is likely linked to another, longer cycle: the formation of Earth's supercontinents every 400 to 600 million years, ...

A new study introduces a novel way for tectonic plates — massive sheets of rock that jostle for position in the Earth’s crust and upper mantle — to bend and sink. It’s a bit of planetary Pilates that ...
