The Earth is four and a half billion years old, so why they started appearing then is unknown, as is the mechanism to make ...

The Earth’s crust is constantly changing. It’s currently made of many huge rock slabs called tectonic plates—seven major ones along with many more smaller plates—that fit together like puzzle pieces ...

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 ...

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 ...

Ancient asteroid impacts may have done more than reshape Earth's surface—they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal ...

It feels like there have been staggering science stories emerging every other day recently, all of which have blown our tiny little minds. First, there was the discovery of a terrifying black hole ...

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 ...
