Important facts about paleomagnetism

Important facts about paleomagnetism respect your woman images Earth, Magnetic Properties of Our planet has the properties of a huge magnet. Like a magnet, it has a positive and a negative pole. These magnetic poles nearly coincide with the planet's geographic poles. Its magnetic field extends thousands of miles into space. Earth's magnetic field is invisible. It consists of a pattern of lines stretching from one pole to the opposite pole.

This record is preserved by many rocks from the time of their formation. The paleomagnetic data have played an instrumental role in deciphering the history of our planet including a decisive evidence for continental drift and global plate tectonics.

Scientists examine the ocean floor and its bands of igneous rock for evidence of magnetic reversals. If some of the bands are pointing south instead of north, it shows that at various points in Earth's history, the magnetic poles reversed. This term is also sometimes used for natural remanent magnetization. Magnetic stripes are the result of reversals of the Earth's field and seafloor spreading.

how does paleomagnetism support seafloor spreading

Did gigantic magnetic reversals occur? If so, why did it happen? What event does it point us to? This is science vs.
