An artistic cross section of the Earth’s outer shell showing the effect of plate tectonics on the surface. Volcanoes form above the place where plates slide – or subduct – over one another.

The interiors of rocky planets and moons tend to be pretty hot compared with their surfaces. This heat, which can be caused by a number of sources — such as tidal stretching and compression, the ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

Scientists have taken a journey back in time to unlock the mysteries of Earth’s early history, using tiny mineral crystals called zircons to study plate tectonics billions of years ago. The research ...

One of Earth’s defining features is its plate tectonics, a phenomenon that shapes the planet’s surface and creates some of its most catastrophic events, like earthquakes, tsunamis, and volcanic ...

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, ...

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 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 ...

The dance of the continents has been reshaping Earth for billions of years, creating the landscapes we walk on today. Scientists are unlocking secrets about how plate tectonics forged our modern world ...
