A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published today in AGU Advances, AGU’s ...

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 ...

Some theories were mocked not because they lacked evidence, but because they challenged what scholars thought they already knew. Alfred Wegener argued that continents moved decades before plate ...

Observations indicate that plate tectonics began before any currently known structural geological record on Earth Identification of the oldest preserved pieces of Earth’s crust in southern Greenland ...

Earth is currently the only planet known to harbor life—thanks in large part due to the operation of plate tectonics, which cycles critical biogeochemical elements and maintains a planetary thermostat ...

Harvard University researchers say they’ve found evidence that the outer layers of the Earth more than 3 billion years ago cracked into shifting tectonic plates, as they are today, adding to a debate ...

Map of the Earth showing tectonic plates. Early Earth likely had no plate tectonics, but a solid outer crust with no tectonic activity covered the entire planet. After being broken up by convection ...

Ancient rocks found by NASA's Perseverance rover reveal Mars was repeatedly impacted by asteroids billions of years ago.

Earth is a dynamic and constantly changing planet. From the formation of mountains and oceans to the eruption of volcanoes, the surface of our planet is in a constant state of flux. At the heart of ...
