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 in the open access journal AGU ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Are we alone, and if so, why? So far, the search for ...

Ancient rocks in Greenland When and how plate tectonics started is a key question among geologists. Some researchers think it started more than 4 billion years ago, and others say it started only ...

New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that ...

Add Yahoo as a preferred source to see more of our stories on Google. When you buy through links on our articles, Future and its syndication partners may earn a commission. Plate tectonics may have ...

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, ...

Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of ...

(CN) — Think the first world wide web is a recent development? Think again. Billions of years before the internet was created, a natural process involving tectonic plates became a global network that ...

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, ...

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 ...

Scientists have taken a journey back in time to unlock the mysteries of Earth’s early history, using tiny mineral crystals called zircons to study plate tectonics billions of years ago. The research ...

Creative destruction: a thinner ocean plate sides under a continental plate, melting and recycling the ocean crust into the Earth’s interior and birthing volcanoes in this illustration of subduction, ...
