The Earth's magnetic poles have reversed multiple times, and predicting a reversal is highly difficult, as the reversals have no specific length or time frame. These reversals can be seen by studying rock layers, particularly those found mid-ocean, which show minerals that display normal and reversed polarity, depending on which side of the ridge the samples are taken from.
