Sea floor spreading occurs at mid-ocean ridges
Scientists found evidence of magnetic stripes on the ocean floor, which indicated periodic reversals in Earth's magnetic field. This discovery helped support the theory of plate tectonics and seafloor spreading.

Sea floor spreading was not known during Wegener's lifetime because the technology to map the ocean floor, such as sonar mapping, did not exist yet. Without this technology, scientists were unable to detect the mid-ocean ridges where sea floor spreading takes place. Additionally, Wegener's theory of continental drift was met with skepticism and not widely accepted during his time, which may have deterred further exploration into related concepts like sea floor spreading.
