Reversal Geomagnetism

Reversal geomagnetism refers to the periodic switching of Earth’s magnetic poles, where the magnetic north and south poles flip places. This phenomenon occurs over geological timescales, typically every several hundred thousand years. Paleomagnetism, the study of these magnetic reversals captured in rocks, helps scientists understand Earth's magnetic history. When volcanic or sedimentary rocks form, they record the direction and intensity of the magnetic field. By examining these records, researchers can trace past pole reversals, providing insight into the dynamics of Earth’s core and the movement of tectonic plates, as well as contributing to our understanding of climate changes over time.
