Magnetic striping and seafloor spreading

WebThe two parts of the oceanic plate are pulled apart, and magnetic stripes become older as they move away from the mid-ocean ridge. The figure shows the spreading ridge about 5 million years ago (a), about 2 to 3 million years ago (b) and nowadays (c). Courtesy of the U.S Geological Survey. Web4.5 Divergent Plate Boundaries Modified from "Physical Geology" by Steven Earle* Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land). The mid-ocean ridge mantle, creating …
