Exactly when and how plate tectonics started, however, is a matter of debate. Now, in a study published March 19 in the ...

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 ...

The arid hills of Western Australia’s Pilbara region contain the earliest evidence yet of tectonic plates sliding across Earth’s surface. Tiny magnetic crystals locked in the bedrock recorded the ...

The rocks didn’t look like much from the outside. Scattered across a remote stretch of western Australia called North Pole Dome, they were ancient, weathered, and largely ignored for the better part ...

Sunken slabs from long-lost tectonic plates are still churning around in Earth's interior, far below your feet. In a new ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Using magnetic traces from ancient pieces of Earth’s crust, researchers found that a chunk of what is now Western Australia ...

Scientists say they have uncovered new clues in Australia about when plate tectonics began on Earth, the only known planet to ...

The history of the Earth is written on the great tablets of tectonic plates. The motions of plates shaped land masses, formed oceans, and created the varied climates and habitats that set the stage ...
