Quizplus · Accepted Answer

The alternating stripes of magnetic field patterns found on the seafloor are a key piece of evidence for seafloor spreading. This phenomenon occurs as magma rises at mid-ocean ridges, cools, and solidifies, recording the Earth's magnetic field direction at the time. As the seafloor spreads, it creates symmetrical patterns of magnetic stripes on either side of the ridge, supporting the theory of plate tectonics.
