Question

How do magnetic patterns in the rocks along the mid-oceanic ridges explain seafloor spreading?

Answer 1

The magnetic reversals are matched exactly either side of the mid-atlantic rift.It's a bit like you painting a load of stripes on half a piece of paper, folding it over, then opening it so that the stripes are a mirror image of each other.
The only way this could have happened is if sea-floor spreading takes place.This was one i had to search for you but i hope it still helps you:))
