A fascinating new study reveals how two of Earth’s established continents may constitute one whole landmass in itself.

Earth surface is covered with rigid plates that move, crash into each other and dive into the planet's interior. But when did this process begin? When you purchase through links on our site, we ...

If real, that version of plate tectonics looks nothing like Earth's. But it shows the diversity of planetary geology that could lurk elsewhere in the cosmos. "In the end, understanding what causes ...

But how unique is our planet's geology? The interiors of rocky planets ... This process, called plate tectonics, is responsible for earthquakes, volcanoes, ocean ridges and vast mountain ranges ...

The answer to the total number of tectonic plates is a matter of who you ask in the field of geology. One thing that scientists can agree on is that there are seven major plates, and they’re ...

Finding evidence of such a giant earthquake so early in Earth’s roughly 4.5-billion-year history throws a spotlight on a hotly debated topic in geology: When did plate tectonics, the constant ...

William Jason Morgan, a leading scholar of plate tectonics and mantle movements, died on July 31 in his sleep, at the home he shared with his daughter and her family. He was 87. Morgan, Princeton ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic ...

While the researchers hint that plate tectonics may have started on Earth soon after 3.4 billion years, the geology community is divided on a specific date. "We think plate tectonics, in the long ...

An earthquake such as this occurs because Earth’s crust is divided into shifting tectonic plates. The forces behind plate tectonics play a part in determining nearly everything about Earth ...

A reappraisal of decades-old data suggests that strange circular formations on Venus could be volcanic “rings of fire” ...
