How do magnetic stripes show the history
WebSep 26, 2024 · The idea was born that lithosphere could be formed along these ridges, and the new material could push plates apart. The ultimate proof of this was the discovery of "magnetic stripes"on the seafloor later in the 1960s: the magnetic domains in oceanic rocks recorded reversal of Earth's magnetic field over time. WebOct 9, 2024 · How does magnetic stripes support seafloor spreading? When lava gets erupted at the mid-ocean ridge axis it cools and turns into hard rock. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. These patterns of stripes provide the history of seafloor spreading.
