Houchin and his colleagues studied dozens of zircon crystals from the Jack Hills in Western Australia. These are the oldest known fragments of Earth rocks. Some date back to the Hadean eon, which ...

Scientists warn that the plate beneath Gibraltar arc will begin to shift toward the Atlantic within 20 million years.

There are many open questions about how our planet formed 4.55 billion years ago: When did plate tectonics start? When did the Earth's mantle begin to vigorously circulate in a process called ...

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 ...

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 ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes, and ...
