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 ...

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

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 ...

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.

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.

COOLING DOWN Newly formed oceanic crust (redder shaded regions) is thinner on average than older crust, new research shows.This thinning suggests that Earth’s mantle is cooling faster than ...

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 ...

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

To come to this conclusion about the process of plate tectonics, the scientists created a new computer model of Earth with the crust and mantle considered as one seamless system. Over time, about ...
