What is a polar shift and its effects?

Answer 1

The magnetic north and south poles shift, and sometimes flip. Flipping has happened countless times in the geological past (last one was 780,000 years ago but there is no real periodicity). There are some indications that perhaps the flip takes a few thousand years and there is a belief that the earths magnetic field declines to zero in between, leaving us less protected from space radiation. But in reality, scientist believe that the field doesn't disappear, just gets complex.

There are no signs of any catastrophic effects in association with any polar reversal in the geological record - things just continue as normal (except for your compass).

Answer 2

The pole are continuously moving somewhat. As they move, the earth's magnetic field moves with them. I suppose that If a pole shifted over say, New York City, It would have negative consequences. The magnetic field traps radiation from the sun and sort of funnels it towards the poles. T the pole, their are higher levels of electromagnetic radiation, hence the Northern lights. These phenomena can disrupt communications and even power grids. If a pole was over a city, the entire city would have to be retrofitted in order to be able to maintain power and communication. Luckily, there is very little chance of this happening to any cities around today because they are not close enough to either of the geographic poles.

Answer 3

It is a change in the axis and the magnetic pole, imagine the pole in north Africa, the effects are catastrofic, pole shift is in constant measure and very likely to happen in few thousand years.

Answer 4

It is a little dress that you wear when you go to either the South or North Pole. Th effect is probably chilly knees.

Answer 5

. . . it's that satisfactory expression that the eskimos use instead of saying "the earth moved!" . . .
