Direct evidence of the movements of tectonic plates has been found in some of the world’s oldest rocks, in the Pilbara Craton, Western Australia. This evidence dates back 3.5 billion years; the ...

Magnetic crystals provide the earliest evidence yet of the plate tectonics that likely made Earth habitable, pushing its start back by 140 million years.

Scientists have uncovered the oldest direct evidence yet that Earth’s tectonic plates were on the move 3.5 billion years ago. By analyzing magnetic fingerprints in ancient rocks, they reconstructed ...

But scientists have debated for decades when this shift began. Some theories suggest that Earth’s crust was a single, rigid shell before it was shattered. A new study has uncovered the oldest evidence ...

Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

For millions of years, Earth’s shifting plates have shaped continents, formed oceans, and built towering mountain ranges. But some of these colossal structures have vanished into the depths of the ...

Researchers in China and Australia have created an animation that details Earth's tectonic movements over the past 1.8 billion years. In just over a minute, the video offers a mesmerizing look at how ...

Earth’s earliest crust may have looked a lot more like the continents we know today than scientists once believed. A recent study shakes up old ideas about how Earth's surface evolved, showing that ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...

Earth is the only known planet which has plate tectonics today. The constant movement of these giant slabs of rock over the planet’s magma creates continents – and may have even helped create life. In ...
