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

These results suggest the existence of a process recycling marine carbon into Earth's mantle, which could contribute to ...

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

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

The oldest crust on Earth, known to be unchanging, is actually being altered in real time. The North American continent is "dripping" rock into the lower layers of the Earth, new research says ...

Continental crust is generally higher in silica, which makes it less dense. This low density makes continents too buoyant to be pulled back into the mantle and they remain floating near the surface.

The physical challenges of drilling to the mantle werey daunting. Scientists went through one of the thinnest possible section of the crust on the ocean bottom, going through about 1400 to 1700 meters ...

For Earth, the explanation is relatively straight forward: we have two types of crust. Oceanic crust that underlies the oceans is thin, dense and low in silica (silicon oxide) while continental crust ...

The impact also releases pressure on the mantle below, causing it to melt and produce a “blob-like” mass of thick basaltic crust. This mass is called an oceanic plateau, similar to that ...

The thickness of continental crust — the part of Earth’s crust that forms land masses and continents — plays an important role in everything from the gradual movement of continents to the evolution of ...
