As the rift valley grows wider, the continent begins to split apart.If the rift valley continues to widen, the thinned valley floor sinkslower and lower until it is below sea level.he records are the same on either side of the ridge.As scientists continued to map the ocean floor, they found morerecords of these reversals.
