The dynamic life of an oceanic plate
WebJun 11, 2024 · The once-massive Farallon oceanic plate, for example, is nearly gone, subducted beneath the North American Plate. Just a few slivers of the Farallon remain, along the Mexican coast, south of Baja California and in the Pacific Northwest. Researchers have been tracking the plate as it sinks ever deeper into the mantle. WebOur planet might seem fixed and rigid, but a closer look reveals that it is constantly shifting under our feet. Delve into the earth's interior, learn about its tectonic plates and their movements, and discover how mountains, volcanoes, and earthquakes are formed. Start your exploration with Earth's Structure.
