Earth’s crust may have gone on the move roughly 3.8 billion years ago. “Earth is actually quite distinct to other planets, in that it has plate tectonics,” says study coauthor Nadja Drabon, a ...

It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...

(Inside Science) — Shifting, slipping and colliding tectonic plates played an essential role in the emergence and evolution of life on Earth. Such tectonic activity generated volcanoes that spewed ...

Houchin and his colleagues studied dozens of zircon crystals from the Jack Hills in Western Australia. These are the oldest ...

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 ...

Plate tectonics may be unique to Earth and may be an essential characteristic of habitable planets. Estimates for its onset range from over 4 billion years ago to just 800 million years ago. A new ...

With tectonic plates bumping and grinding against each other, Earth is a pretty active planet. But when did this activity begin? A new study from Yale University claims to have found evidence that ...

A post–World War II data boom clinched the unifying theory of plate tectonics after decades of debate over whether Earth’s crust was static or mobile, Carolyn Gramling reported in “Shaking up Earth” ...

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 ...
