Paleomagnetism

=__Paleomagnetism__= ====Paleomagnestism is the Earth's magnetic field. Rocks actually have magnetic field. But thorughout the years, the magnetic field on the rocks have changed. The minerals in the rock are now having different magnetic fields. The Earth's magnetic field has not pointed north, as it does now. The rock's magnetic field are parallel to the Earth's magnetic field at the time of their formation. When the magnetized minerals becomes separated from their parents rocks by erosion and are carried into a basin. The the magnetic field will tend to align themselves parallel to the Earth's magnetic field as they settle in the water.The magnetic field reversal are recorded in the deep bottom ocean materials. In the deep ocean bottom gives clues that at some ancient times, the Earth's magnetic poles have reversed. The magnetic field on the rocks are now South Pole and North Pole instead of North Pole and South Pole. The Earth's magnetic field is generated by rotating of electrical field of Earth's outer core.====
