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.

A paper published this week in <em>Science</em> uses diamonds to paint a new picture of the early Earth—one where plate tectonics didn't work like it does now.

Scientists are constantly on a mission to untangle how Earth alone among the planets was able to evolve complex life. We know that Earth's past internal movements of the tectonic plates under our feet ...

Earth's surface is broken up into large plates that rub against each other, causing earthquakes, volcanoes and large mountain ranges. But how unique is our planet's geology? When you purchase through ...

Researchers have produced a new estimate for the origin of Earth's plate tectonics—the movement of large chunks of the planet's outer layer, or crust. Although there is broad consensus that plate ...

The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

Which forces and mechanisms determine the height of mountains? A group of researchers has now found a surprising answer: It is not erosion and weathering of rocks that determine the upper limit of ...

A massive 37-million-year-old underwater canyon reveals the fossil trace of an ancient Atlantic tectonic boundary.
