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 ...

Tectonic plates — which divide Earth’s crust and reshape our planet in an ongoing, dynamic process — may be the key to supporting life. In fact, because Earth is the only planet known to be home to ...

Our planet is in constant flux. Tectonic plates—the large slabs of rock that divide Earth’s crust so that it looks like a cracked eggshell—jostle about in fits and starts that continuously reshape our ...

Geoscientists from the University of Toronto have made a breakthrough discovery that adds new dimensions to the theory of plate tectonics. Their research, published in Geophysical Research Letters, ...

Rocks in Australia preserve evidence that plates in Earth’s crust were moving 3.5 billion years ago, a finding that pushes back the beginnings of plate tectonics by hundreds of millions of years.

A gravity gradient model of the central Indian Ocean shows the junction of the African tectonic plate (left), the Indo-Australian plate (right) and the Antarctic plate (bottom). Credit: Scripps ...

A high-resolution map of Mars's entire magnetic field provides new evidence that Earth-like plate tectonics - great crustal plates pulling apart and crashing together - underpin the red planet's ...

A geologist has revealed intriguing insights into the volcanic activity on Mars. He proposes that Mars has significantly more diverse volcanism than previously realized, driven by an early form of ...

A new study has revealed that tectonic activity on Venus may have caused sections of the planet's upper crust to become fragmented into smaller bodies that, over vast swathes of time, barge past each ...
