Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

Our planet was born around 4.5 billion years ago. To understand this mind-bendingly long history, we need to study rocks and the minerals they are made of. The oldest rocks in Australia, which are ...

The Earth’s crust is constantly rewritten by volcanoes, erosion, and plate tectonics. New crust is being created while old ...

Stable parts of the Earth's crust may not be as immovable as previously thought. While much of the crust is affected by plate tectonic activity, certain more stable portions have remained unchanged ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...

When most of us think about what shaped our planet, we probably picture volcanoes, earthquakes, and huge continents slowly drifting apart (or back together again) over millions or billions of years.

TEMPE, Ariz. — Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and ...

Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth’s crust but in our planet’s mantle, the layer sandwiched between the thin crust and Earth ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...
