WebTheory: Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός “pertaining to building”) is a scientific theory describing the large-scale motion of 7 large plates and the movements of a larger number of smaller plates of the Earth‘s lithosphere, over the last hundreds of millions of years. Web27 de set. de 2024 · In hot spots beneath the ocean, the tectonic activity creates a volcanic mound. Over millions of years, volcanic mounds can grow until they reach sea level and create a volcanic island. The volcanic island moves as part of its tectonic plate. The hot spot stays put, however.

WebAbout 150 million years ago, a rift opened up within the supercontinent called Pangaea. New crust formed along the underwater Mid-Atlantic Ridge. This change drove the breakup of Pangaea—and formed the Atlantic ocean. The continents we know today as Europe and North America separated first, followed by South America and Africa. WebAs upwelling of magma continues, the plates continue to diverge, a process known as seafloor spreading. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading …
