A new study from Harvard geoscientists reports the oldest direct evidence yet of plate motion, dating to 3.5 billion years ago. In a study published March 19 in Science, the researchers found that ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...

An exceptionally well-preserved skull from a fish which lived 384–382 million years ago helps explain how plate tectonics played a key role in the evolution of ancient bony fish which eventually led ...

Using information from inside the rocks on Earth’s surface, my colleagues and I have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth’s ...

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 ...

I just returned home from an adventure in Ecuador, the highlight was two weeks on a boat exploring the Galápagos Islands. As an earth scientist, there’s always a geologic story wherever I visit, but ...

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 ...
