An enduring question in geology is when Earth’s tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ...

Scientists have uncovered the oldest direct evidence yet that Earth’s tectonic plates were on the move 3.5 billion years ago.

An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ...

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

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 ...

Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

"There's a lot of work that seems to suggest that early in Earth's history plate tectonics wasn't actually the dominant way in which the planet's internal heat gets released as it is today through the ...

The Pontus oceanic plate that was reconstructed by Suzanna van de Lagemaat: its location in the paleo-Pacific ocean 120 million years ago, and its present relicts. An earlier study showed that a large ...

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 ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

It is common knowledge that mountain ranges were created by tectonic forces, but how their height is maintained today is a matter of debate. A widely held view is that climate-controlled erosion ...
