The result of the addition of new sea floor rock is that the Atlantic Ocean between these sets of continents is widening. North and South America move farther away from Eurasia and Africa each year. The youngest sea floor rocks are found in the middle of the ocean because that is where new sea floor is added.ackground. Sea floor spreading is one component of the theory of plate tectonics. According to this concept, at ridges in many of the world's oceans (mid-ocean ridges), new crustal rock is added to the edges of plates on either side of the mid-ocean ridge.
