Magnetic Reversal Definition Geology at Bo Owens blog

Magnetic Reversal Definition Geology. every half million years, on the average, the earth's magnetic polarity reverses, and so does the magnetization of the ocean floor. When lavas or sediments solidify, they often preserve a signature of the ambient. liquid lava, which hardens into rock, contains grains of iron oxides that react to the earth's magnetic field by pointing toward the magnetic pole as the rock solidifies. We can see evidence of magnetic polarity reversals by examining the geologic record. what do we mean by a magnetic reversal or a magnetic 'flip' of the earth? magnetic field reversal refers to the phenomenon where the earth's magnetic north and south poles switch places over. The earth has a magnetic field, as can be seen by using a magnetic compass. geomagnetic reversal, an alternation of the earth’s magnetic polarity in geologic time. records indicate that over the last 160 million years, the magnetic pole has reversed its polarity at least several hundred times.
