How does geomagnetism provide support for seafloor spreading?
A) Magnetic particles in basalt orient with the magnetic field in force at the time the oceanic lava cooled and hardened; the magnetic pattern is the same on both sides of the ridge. B) Mantle hot spots are always oriented to the magnetic field. C) The ocean floor is uniformly old, preserving the Earth's 4.6 billion history including past reversals in polarity. D) The oldest oceanic crust is always found near mid-ocean ridges. As one moves out from these ridges, the crust is simultaneously younger and oriented according to the polarity at the time. E) Isotopic analysis of ocean core sediments help determine sea floor age and this can be used to infer past magnetism.
