Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping s â¦ ediment become younger as the mid-ocean ridge is approached.Also, the rock that makes up the floor of the ocean is younger than the continents.27 people found this useful.amples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping s â¦ ediment become younger as the mid-ocean ridge is approached.
