Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

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 ...

The first ruptures in early Earth’s skin formed because of the weakness of rock minerals merely a millimeter wide, two scientists propose. The small minerals’ behavior created boundaries defining ...

Add Yahoo as a preferred source to see more of our stories on Google. Map of Earth's principal tectonic plates. Earth's lithosphere. Major and minor plates. arrows indicate direction of movement at ...

Earth's surface is covered by more than a dozen tectonic plates, and in subduction zones around the world—including the ...

Plate tectonics is the theory used to explain the structure of the Earth’s crust and many of the associated phenomenon. The rigid lithosphere is split into 15 major plates that slowly move on top of ...

The Earth's plates jostle about in fits and starts that are punctuated with earthquakes and volcanic eruptions. 4 min read There are a few handfuls of major plates and dozens of smaller, or minor, ...

The outer layer of modern Earth is a collection of interlocking rigid plates, as seen in this illustration. These plates grind together, sliding past or dipping beneath one another, giving rise to ...

Scientists are constantly on a mission to untangle how Earth alone among the planets was able to evolve complex life. We know that Earth's past internal movements of the tectonic plates under our feet ...

Geoscientists have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas of Earth's crust long before it should be geologically altered by known plate-boundary ...
