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.

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.

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 crust of Earth, the planet's outer shell, is divided into two rough categories: The older, thicker continental crust; and the younger, denser oceanic crust.

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.
