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 continental crust is the layer of granitic, sedimentary and metamorphic rock that forms the continents. This crust is very thick compared to oceanic crust which forms part of the outermost ...

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 ...

There is evidence that 60-70% of the Earth's continental crust was formed by around 3 billion years ago. It continues to grow today, but at rates that are more than 3 times slower. Most of that growth ...

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

Anyone with a map can see that Asia and Europe are connected. ... Geologists are still arguing what these discoveries about continental and oceanic crust mean for the number of continents.

Continental crust — which is made of less dense rock than oceanic crust and therefore rises to higher elevations — came perhaps hundreds of millions of years later.

Some areas of continental crust have maintained long-term stability from the beginning of Earth's history, with little destruction by tectonic events or mantle convection, known as cratons. Phys.org ...

That’s all thanks to the lithosphere, a solid layer of crust and part of the upper mantle that’s broken into more than a dozen slabs, or plates, of varying sizes. These pieces, divided between older ...

The data covered 560 miles (900 km) of the boundary between the continental North American plate and the oceanic plates Juan de Fuca, Explorer and Gorda, all of which are plunging beneath North ...
