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 ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. A new study, using a combination of old models, new geophysical ...

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 ...

The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

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, ...

Scientists have taken a journey back in time to unlock the mysteries of Earth’s early history, using tiny mineral crystals called zircons to study plate tectonics billions of years ago. The research ...

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 ...

For millions of years, Earth’s shifting plates have shaped continents, formed oceans, and built towering mountain ranges. But ...
