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

The rocks didn’t look like much from the outside. Scattered across a remote stretch of western Australia called North Pole ...

The history of Earth is written on the great tablets of tectonic plates. The motions of plates shaped land masses, formed ...

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

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 ...

Scientists have uncovered the oldest direct evidence yet that Earth’s tectonic plates were on the move 3.5 billion years ago.

About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...

Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

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 ...

Magnetic crystals provide the earliest evidence yet of the plate tectonics that likely made Earth habitable, pushing its ...

At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from belowground force ...

BUFFALO, N.Y. — At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from ...
