Researchers analyzing ancient deposits in Australia found evidence that Earth's layers started to get mixed up — a fingerprint of plate tectonics — about 1.3 billion years after the planet formed.

Earth’s surface is constantly shifting, shaped by the slow but powerful movement of tectonic plates. While some plates have persisted for hundreds of millions of years, others have vanished, sinking ...

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 ...
