Exactly when and how plate tectonics started, however, is a matter of debate. Now, in a study published March 19 in the ...

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.

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 ...

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 ...

Map of the Earth showing tectonic plates. Early Earth likely had no plate tectonics, but a solid outer crust with no tectonic activity covered the entire planet. After being broken up by convection ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...

Researchers have discovered the world's oldest known arc-slicing fault in Australia, intensifying the debate over the origins of plate tectonics. When you purchase through links on our site, we may ...

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 ...

Minerals suggest large blocks of Earth’s crust moved around as early as 3.2 billion years ago Modern plate tectonics may have gotten under way as early as 3.2 billion years ago, about 400 million ...
