Seafloor Spreading

In this video, we take a look at the concept of seafloor spreading and the four major pieces of evidence that support it, with a focus on the observed alternating bands of magnetism preserved in the rock on either side of a mid-ocean ridge.

    But what causes the cycles of the earths double torus magnetosphere to increase causing magma to well up every 12,000 years for a 1,000 years? Continental drift should be called continental rebound after Noah's tidal wave deluges hit up against Africa pushing the mid Atlantic ridge up and tearing the Pacific ring of fire apart. The galactic Milankovitch cycles not you or co2 causes climate trends and this the millennium of climate change END TIMES. Jesus God warned us.

    Very nice video, many good pieces of information. However, I would argue that "supporting evidence #3" is better explained by proximity to continental masses than distance from ridges. The sediments come from erosion of areas above seawater. As you can see from the map shown, there is no consistent difference until very close to shore

    I'm curious why you didn't talk about the west coast of North America and how that is all newer rock. I'm also wondering why there is no build up of sediment on the west coast if the continent is being pushed west by the seafloor spreading in the Atlantic. Shouldn't there be subduction on the west coat, which would leave sediment build up?

    The magnetic bands all have the magnetic field in the same direction. We only have alternating patterns of strength and weakness in the same direction. Wouldn't electromagnetic standing waves produce the same artifacts? With the reversal theory, the magnetic poles have to reverse. Can anyone think how this is possible ?
