In two recent studies, researchers suggest a weakening ocean current system is to blame for a persistent cold spot in the ...

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

The oldest oceanic plates on Earth date back about 200 million years. In contrast, the crust of continents lies under shallow oceans and land. It is highly variable in composition and age.

The crust making up Zealandia is between 10 and 30 kilometers thick, making it thicker than the seven kilometers of most ocean crust. But it is not as thick as other continents’ crust, typically ...

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 ...

Continental crust is on average five times thicker than oceanic crust, and it tends to be far more ancient. Whereas the oldest known oceanic plates are around 200 million years old, more than half of ...

New continental crust forms when its building blocks are passed to Earth's surface from continental arc volcanoes. These are found in parts of the globe where oceanic plates sink beneath ...

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 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 ...
