Based on a series of models considering how the continents were assembled over time, a team of researchers at the University of Adelaide created an updated map of Earth's tectonic plates. The map will ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year over millennia. When plate tectonics first emerged ...

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 ...

One of Earth’s defining features is its plate tectonics, a phenomenon that shapes the planet’s surface and creates some of its most catastrophic events, like earthquakes, tsunamis, and volcanic ...

A comprehensive study suggests the Arabian plate is geologically stable and capable of withstanding long-term forces from surrounding tectonic activity. To better understand the earthquake hazards ...

Some 4.5 billion years ago, a Mars-sized object smashed into the nascent Earth, spinning off our moon. Now a team of scientists proposes this giant impact did even more: The collision left behind ...
