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 ...
When you buy through links on our articles, Future and its syndication partners may earn a commission. Plate tectonics is the means through which mountains are formed. The Baird Mountains in Alaska’s ...
To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine is ...
Using information from inside the rocks on Earth’s surface, my colleagues and I have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth’s ...
In 2016, the geochemists Jonas Tusch and Carsten Münker hammered a thousand pounds of rock from the Australian Outback and airfreighted it home to Cologne, Germany. Five years of sawing, crushing, ...
It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...
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. These ...
Direct evidence of the movements of tectonic plates has been found in some of the world’s oldest rocks, in the Pilbara Craton, Western Australia. This evidence dates back 3.5 billion years; the ...
The early Earth may have looked much like Iceland—where lava fields stretch as far as the eye can see, inky mountainsides tower above the clouds and stark black sand beaches outline the land. But the ...
Generally speaking, it’s easy enough to make sense of the last few million years of climate patterns—the world looked much as it does today, so changes in greenhouse gas concentrations or ocean ...
On September 7, 2017, a magnitude 8.2 earthquake struck southern Mexico, killing dozens and injuring hundreds. While earthquakes are common enough in the region, this powerful event wasn’t any ...
