The hypothesis of continental drift came up in 1910 by German scientist Alfred Wegener. The idea is that when you look at a map south America and Africa seem to fit perfectly together. this would have made one super Continent called Pangaea. so in order for it to get to where it is today something must have happened that is where the idea of floating continents came in. this theory is no longer relevant as now scientists found they would have to adjust to fit the size if both continents. I hope this helps.
