New research from HKU geologists suggests that Earth's first continents were born not from plate tectonics, but from deep ...

When plates collide, oceanic crust will be subducted under continental crust, recycling it back into the mantle. Therefore, oceanic crust never gets to age as much as continental crust, which almost ...

This "virtual Earth" is the first computer model that "views" the crust and mantle as an interconnected, dynamic system, the researchers reported Oct. 30 in the journal Science Advances.

The Earth’s crust is disappearing right beneath our feet – and most people don’t even realise it. Now, if you’re a geologist, ...

Oceanic crust formation is dynamic after all Date: November 29, 2009 Source: Brown University Summary: Earth scientists have found strong evidence that the geological processes that lead to the ...

At mid-ocean ridges at the bottom ocean, where plates drift apart, new oceanic crust is constantly produced as basaltic rocks when hot volcanic lava emerges from the mantle and solidifies.

Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...

The hot mantle churns and circulates, moving the crust at the surface, causing the oceanic crust to dive into its depths — a process called subduction — and triggering the upwelling of vast ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate ...

The crust is the outermost layer of Earth above the mantle. As discussed earlier, crust can be divided into two types: continental crust and oceanic crust. The continental crust ranges from 25 to 70 ...

A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.
