What are paleomagnetism and magnetic field reversals?

Answer:

Paleomagnetism refers to the strength and orientation of the earth's magnetic field at some remote past time. Magnetic field reversals are recorded in deep ocean bottom materials which show that at some ancient times the earth's magnetic poles have reversed, north pole becoming south pole and south pole becoming north pole.
