What does paleomagnetism prove about the ocean floor?

Europe and North America show different poles because they were in different positions than they are today. Hence, data from paleomagnetism finally ended the debate over continental drift. All of the early evidence for continental drift came from the continents. read more

The main finding from mapping the magnetism of the ocean floor is that the ocean floor is created at mid-ocean ridges, more or less symmetricly spreads away from the ridges, and is finally subducted under continents or deep ocean troughs. It is the main evidence supporting plate tectonics. read more
