New understanding of terrestrial formation has significant and far reaching future implications
The current theory of continental drift provides a good model for understanding terrestrial processes through history. However, while plate tectonics is able to successfully shed light on processes up to 3 billion years ago, ...

Zircon crystals reveal onset of plate tectonics
(Phys.org) -- We're familiar with the theory that the Earth's crust is composed of tectonic plates that move, sometimes dramatically to create earthquakes and tsunamis - but until recently, nobody knew how ...

Landslides linked to plate tectonics create the steepest mountain terrain
Some of the steepest mountain slopes in the world got that way because of the interplay between terrain uplift associated with plate tectonics and powerful streams cutting into hillsides, leading to erosion ...

Copper chains: Study reveals Earth's deep-seated hold on copper
Earth is clingy when it comes to copper. A new Rice University study this week in the journal Science finds that nature conspires at scales both large and small -- from the realms of tectonic plates down t ...

New understanding of Earth's lithosphere-asthenosphere boundary beneath the Pacific Ocean
Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth's crust: the lithosphere and underlying asthenosphere. ...

Model describes New Zealand's complex tectonic environment
At the Hikurangi fault, off the eastern coast of New Zealand's North Island, the Pacific tectonic plate sinks beneath the Australian plate. Farther south, in the Marlborough Fault System, which cuts through the country's ...

Unexpected earthquakes within continental plates pose challenges
Earthquakes that occur on "passive" continental margins, such as the August 2011 magnitude 5.8 Mineral, Virginia, earthquake, surprise people because they expect earthquakes to occur only on plate boundaries. But, in fact, ...

In Japan, seismic waves slower after rain, large earthquakes
An earthquake is first detected by the abrupt side-to-side jolt of a passing primary wave. Lagging only slightly behind are shear waves, which radiate out from the earthquake's epicenter and are seen at the surface as a rolling ...
