When it comes to 3-D puzzles, Rubik's Cube pales in comparison with the latest creation from a team of geophysicists. They have just put the finishing touches on a 20-year effort to precisely describe ...

Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents in motion and drives life on Earth. But what ...

Papers presented in a special symposium at the joint annual meeting of the Geological and Mineralogical Associations of Canada at St. John's in May, 1974. Tectonic settings for emplacement of ...

The emergence of plate tectonics is arguably Earth’s defining moment, the authors of a new Nature paper write. Out of all the planets we’ve looked at carefully, Earth is the only one that has a hard ...

A map of gravity variations on the Earth's seafloor, which mostly correspond to underwater ridges and the edges of Earth's tectonic plates. NASA Earth Observatory Plate tectonics may not be a ...

Geoscientists have long puzzled over the mechanism that created the Tibetan Plateau, but a new study finds that the landform's history may be controlled primarily by the strength of the tectonic ...

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 ...

There's something weird going on in the Atlantic Ocean. Off the coast of Portugal, a tectonic plate may be peeling apart, with the top layer separating from the bottom, a scientist has proposed. João ...

A cold, crusty shell of a planet that regularly kills off its occupants with violent earthquakes and massive volcanic eruptions doesn't sound like ideal habitat. But Earth's grinding plates, the ...
