Richards and Song's finding might also help scientists explain so-called " geomagnetic reversals " or " flips ."
12.
A polarity excursion, which can be either global or local, is a shorter-lived version of a geomagnetic reversal.
13.
But over the eons, magnetic dominance has flipped many times to the south pole, a change called geomagnetic reversal.
14.
A polarity excursion is a shorter-lived version of a geomagnetic reversal; polarity excursions can be either global or local.
15.
:: I'm guessing she's referring to the geomagnetic reversal, which is a " flip " of the magnetic axis.
16.
The latter received attention because it successfully reproduced some of the characteristics of the Earth's field, including geomagnetic reversals.
17.
:: : There are two kinds of geophysical event which can affect 14C production : geomagnetic reversals and polarity excursions.
18.
Together, they must save the world from a geomagnetic reversal that will leave the planet vulnerable to lethal solar radiation.
19.
The latter received significant attention because it successfully reproduced some of the characteristics of the Earth's field, including geomagnetic reversals.
20.
In it, there was reference to Geomagnetic reversal and catastrophic ( environmental, geologic, etc . ) results when this occurs.
