Thin oceanic crust is formed by decompression melting of the upper mantle at mid-ocean ridges, but the origin of the thick and buoyant continental crust is enigmatic. Juvenile continental crust ...

The oceanic crust is made of younger rocks than continental crust. This is because oceanic crust is created at mid-ocean ridges. When plates collide, oceanic crust will be subducted under continental ...

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

The different parts of the Earth are the crust, mantle, outer core, and inner core. ... Earth's crust ranges from 5 to 60 kilometers depending on oceanic versus continental crust; ...

On land, continental crust, once created, can remain more or less unaltered for billions of years. But the oldest oceanic crust is only about 200 million years old, as new crust is continually ...

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

Continental crust is also less dense than oceanic crust, though it is considerably thicker; mostly 35 to 40 km versus the average oceanic thickness of around 7-10 km. About 40% of the Earth's ...

The boundary between the brittle part of the upper mantle and the crust (both oceanic and continental) is known as the Mohorovičić Discontinuity (Moho) according to Geology.com.

Currently oceanic crust forms by the eruption of basaltic lava along a globe-encircling network of mid-ocean ridges. More than 18 cubic kilometers of rock are produced every year by this process.

From early Earth history, the continental crust (the Earth's thick solid outer skin that we live on) has accumulated mass from the underlying hot mantle. Most of the newly formed crust, however ...

Because that the basaltic oceanic crust with a lower density than the normal mantle has negative buoyancy near the 660-km discontinuity, so that it may be gravitationally trapped in this region.
