Who do earths magnetic signatures support the idea that continents move

Lets see what I know.

            Alfred Wegener was the first person to discover magnetic signatures

                         
                
                                    The technique focuses on the magnetic signature formed when magma fills in cracks formed as continental plates move. 
            Alfred Wegener said “All we need to do is measure the amounts of uranium and lead very precisely because young-earth creationists certainly support the idea that the continents were once arranged differently like a puzzle.

Hope this helped
