How does new oceanic crust form

WebMar 13, 2024 · New crust is formed at divergent boundaries on the ocean floor where the lithosphere is thin. Magma from the upper mantle presses against the plate, pushing it upward, then flows off in opposite directions at the plate. The plate, constructed of brittle lithosphere rock, is stretched by the movement of the convection and soon cracks. WebApr 26, 2012 · Scientists have thought that magmas that form new crust at fast-spreading ridges rise up from the depths, quickly crystallize, and then push away from the ridge to form new ocean floor.
