Computer simulations suggest that a collision with another planetary object early in Earth’s history may have provided the heat to set off plate tectonics. By Lucas Joel Some 4.5 billion years ago, ...

For the first time, scientists have watched a subduction zone literally fall apart beneath the ocean floor. Using advanced ...

An ancient underwater volcano riding a sinking tectonic plate off the coast of Japan may have unleashed several unexplained major earthquakes — by grinding against another tectonic plate above it, a ...

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 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 ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

Scientists have uncovered one of the most exciting geological discoveries of the decade – the long-lost Pontus tectonic plate. This ancient “mega plate,” which once spanned an astonishing 15 million ...
