Could magnetic reversals be caused by meteorite impacts, comet impacts, melting ice caps, or planetary alignments?

Large meteorite impacting the Earth.Although extremely unlikely, it might be possible for a reversal of the Earth's magnetic field to be triggered by a meteorite or comet impact, or even for it to be caused by something more "gentle," such as the melting of the polar ice caps.

But self-contained dynamic systems like Earth’s dynamo can do this without any outside influence. Reversals of Earth's magnetic field can simply happen.
