Plate tectonics is a scientific theory describing the large-scale motion of seven or eight large plates (depending on how they are defined) and the movements of a larger number of smaller plates of ...

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 crust ...

Modern life can feel dizzying, like everything is motion and change. But there are some constants we set our lives against: the relative position of the stars wheeling above, the mountaintops below, ...

BUFFALO, N.Y. — Margarete Jadamec, a University at Buffalo expert on Alaskan plate tectonics, is available to discuss the 7.0 earthquake in the Anchorage area, and how the region’s unique geology ...

This period was anything but boring. There was a time in Earth’s history that was so stable, geologists once called it the Boring Billion. But the fact is, this period was anything but boring. In fact ...

Researchers have produced a new estimate for the origin of Earth's plate tectonics—the movement of large chunks of the planet's outer layer, or crust. Although there is broad consensus that plate ...

Scientists examining rocks older than 3 billion years discovered that the Earth's tectonic plates move around today much as they did between 2 and 4 billion years ago. The findings suggest that the ...
