Researchers believe the core region under southern Africa may actually be the birthplace of recent and likely future pole reversals
Earth has settled in the last 20 million years into a pattern of a pole reversal
about every 200,000 to 300,000 years, although it has been more than twice that long since the last reversal.
12) you learned about Earth's weakening magnetic field and the possibility of a pole reversal
in the distant future.
However, Kirschvink says there is some doubt as to whether the recent reports on the current weakening of the magnetic field point to an imminent pole reversal
combined with water recycling eliminates pH and ionic gradient buildup as well as stopping soil drying from nonuniform voltage gradients.
We know of about 170 pole reversals
over the last 100 million years.
