A geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged. The Earth's field has alternated between period...
Polarity is used to describe the location of the magnetic north pole and where it is
presently located geographically.
The surprising finding was that the ocean floor contained stripes of rock with
different polarities. So, some of the stripes of ocean floor would have
The Geomagnetic Polarity Time Scale (GPTS) has been constructed from an
analysis of ... Black represents
Hence, the Earth has experienced periods of reversed polarity alternating with
times (like now) of
As more maps were made, scientists revealed a zebra-like pattern on the ocean
floor of rocks with either
Currently, the Earth's magnetic north pole is located in the direction of the Earth's
geographic south pole. This is referred to as

The polarity can be "normal" or "reversed."
When the field points toward the north magnetic pole, as it does today, the field
and the rocks that record it have “
