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

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

Early in Earth’s history, the heat left over from the collision that formed the Moon left its surface an ocean of magma. As it cooled, its crust was frequently shattered by massive impacts that ...

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 ...

Have tectonic plates changed speed over the last 3 billion years? The answer has far-reaching implications, as plate tectonics affected everything from the supply of vital nutrients for early life to ...

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 ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

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 ...

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

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 ...
