How is sea floor spreading created
Web22 jul. 2024 · Magnetic reversals occur every so often. When they happen the Earth’s magnetic field reverses its polarity. In other words north becomes south and south becomes north. Magnetic reversal proves seafloor spreading because we can see the polarity of the Earth’s magnetic field in rocks. WebIn this way, as the plates move further apart new ocean lithosphere is formed at the ridge and the ocean basin gets wider. This process is known as “sea floor spreading” and results in a symmetrical alignment of the rocks of the ocean floor …

The oldest … Web16 dec. 2024 · The concept of Sea Floor Spreading Harry Hess proposed the idea of See Floor Spreading. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. Basaltic magma rises from the fractures and cools on the ocean floor to form new seafloor.
