At a transform boundary, two portions of newly formed crust move laterally past each other due to the motion of tectonic plates. As magma rises at the mid-ocean ridge, it creates new oceanic crust, which then becomes offset by the transform fault. This lateral movement allows the sections of crust on either side of the transform boundary to shift in opposite directions, maintaining the overall process of seafloor spreading while accommodating the differences in plate movement. The transform boundary effectively acts as a conduit for the movement of crustal material between the segments of the ridge.
