Explain how an isochron map of the ocean floor supports the theory of seafloor spreading?
An isochron is a line on a map that connects points that have the same age. An isochron map of the ocean floor supports the theory of seafloor spreading because it shows the older rock near the deep sea trenches and the younger rocks near ocean ridges.
