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 ...

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 ...

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 ...
