If the Earths magnettic field reversed? (pole shift)?

Question

Then the tectonic plates would start moving in the other direction right? Would it start out at a much faster speed, or would this happen slow and gradual. Would there be earthquakes all over or would the change be unnoticeable? Would the barrier that stops much of the radiation from space be let down for a couple seconds allowing a lot of damage to the Earth? Then the fault line would be dividing in Australia and coming together in the Atlantic and causing the canal between Egypt and the Arab nations to close again? Of course this would take a long time right, but I want to know all the juicy details if you can please assist me. Thank you.

Answer 1

Ah, not quite.

You see tectonic plates move because of convection currents in the magma underneath the crust of the earth. So, the reversal of the magnetic field would not affect it.

About the natural disasters, I don't see any reason for earthquakes or storms to occur because of it.

Also about the barrier disappearing for a few seconds, would not happen. The magnetic barrier would not sudden disappear and reappear flowing in the other direction. As the geomagnetic reversal occurs (as the scientists call it) the magnetic barrier weakens, but not to the point of nonexistence. Then after it has completed switching, then the barrier quickly recovers back to it's strength.

Actually switching occurs (well according to the most recent theory) because of the liquid core of the earth. As it seems to be able to cause disorganization in the magnetic barrier.

Quite contradictory to Hollywood's version eh?

Answer 2

The movement of the tectonic plates is because of the movement of molten magma within the Earth. The magnetic poles don't affect the movement of the tectonic plates.

No one really knows what happens when the poles reverse because humans were not on earth the last time it happened. The worst thing that would happen is the communication and positioning equipment would experience major interference.

image voltaic flares are an exciting subjects somewhat for the only that is expected in 2012. A image voltaic hurricane is rather unpredictable by way of fact no person is attentive to even the remarkable scientists at NASA or the different area business enterprise no while, the place and how huge a image voltaic hurricane could be. yet its made by utilising a end it rather is made upon the suggestions they have accrued and used over one among those super variety of years to calculate while there may be a available end that there may be a "huge image voltaic Flare" in 2012. So if there became a image voltaic flare what may be the strategic plan ? properly we could desire to place it into perspective each and each affected united states of america could desire a strategic plan and the main extreme one can be risk-free practices of its united states of america and native land against threats of terrorism and political violence even conflict and civil unrest marshal regulation may be a precedence, governments could ought to make confident they became in a position priorities and be waiting to maintain a central authority to run the country and have been waiting to grant the amenity's of sup lies which comprise saving stocked ingredients, operative public centers ( hearth, Police, Paramedic, military). If the extra severe became to ensue it does no longer mean you would be thrown lower back the the dark an prolonged time yet once you skinny approximately it prevalent technologies we use could substitute into usable for a on an analogous time as so the capacity of on a daily basis existence and verbal replace may be pushed lower back to the era of what our older era, gran mothers and dads could have used.

And my compass wouldn't work anymore! I'll be put to the trouble of taking it apart and painting the OTHER ends black and red.
