The concurrent subduction of the Pacific and Atlantic plates resulted in the formation of a mantle plum and the ascent of magma. Credit: Nicolas Riel Earthquakes and volcanism occur as a result of ...

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 ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

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 ...

For millions of years, Earth’s shifting plates have shaped continents, formed oceans, and built towering mountain ranges. But some of these colossal structures have vanished into the depths of the ...

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 ...
