Nov 29, 2023 · Learn how seafloor spreading is a geologic process in which tectonic plates split apart and form new oceanic crust along mid-ocean ridges. Explore the features, mechanisms, and effects of seafloor spreading on Earth's lithosphere, magnetism, and sea level.
Seafloor spreading. Age of oceanic lithosphere; youngest (light colour) is along spreading centers. Seafloor spreading, or seafloor spread, is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Seafloor spreading is the theory that oceanic crust forms along mid-ocean ridges and moves away from them, creating new ocean floor and drifting continents. Learn about the history, evidence, and process of seafloor spreading, and how it relates to plate tectonics.

Seafloor-spreading rates are much more rapid in the Pacific Ocean than in the Atlantic and Indian oceans. At spreading rates of about 15 cm (6 inches) per year, the entire crust beneath the Pacific Ocean (about 15,000 km [9,300 miles] wide) could be produced in 100 million years.
Apr 23, 2021 · Our model proposes continuous seafloor spreading in the entire Red Sea Basin that started all along the Red Sea Rift at least 12–13 Ma. This more than doubles the age of the oceanic crust so...

Jan 1, 2021 · Learn about the mechanism, history, and evidence of seafloor spreading, the process by which new oceanic lithosphere is created and moves away from mid-ocean ridges. Explore how seafloor spreading led to the plate tectonics revolution and the discovery of magnetic stripes, transform faults, and subduction zones.
Learn how the discovery of seafloor spreading and the Mid-Atlantic Ridge helped scientists develop the theory of plate tectonics. Explore how the Earth's crust is born, moves and recycles at divergent and convergent boundaries.
