Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. Researchers had previously identified ...

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 ...

Due to the radiative thermal conductivity of the mineral olivine, only oceanic plates over 60 million years old and subducting at more than 10 centimeters per year remain sufficiently cold to ...

Computer simulations suggest that a collision with another planetary object early in Earth’s history may have provided the heat to set off plate tectonics. By Lucas Joel Some 4.5 billion years ago, ...

Earth's surface is broken up into large plates that rub against each other, causing earthquakes, volcanoes and large mountain ranges. But how unique is our planet's geology? When you purchase through ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

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 ...

The theory of Plate tectonics – developed from Alfred Wegener’s theory of Continental Drift to explain the movement of the continents – has become the prevailing theory underpinning our understanding ...

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, ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...
