WebPaleomagnetism is the study of Earth's magnetic field using Earth's rocks as records. These rocks can have magnetic properties that geologists study to record the history of the magnetic field. Rocks that contain minerals that respond to magnetic fields align with the magnetic field thereby preserving the position of the magnetic field.

Paleomagnetism (occasionally palaeomagnetism ) is the study of magnetic fields recorded in rocks, sediment, or archeological materials. Geophysicists who specialize in paleomagnetism are called paleomagnetists. Certain magnetic minerals in rocks can record the direction and intensity of Earth's magnetic field at the time they formed. This record provides information on the past behavior of the geomagnetic … WebSlab pull is the pulling force exerted by a cold, dense oceanic plate plunging into the mantle due to its own weight.
