What statement most accurately describes the theory of seafloor spreading?
A)Subduction zones produce oceanic crust that moves away from these zones by seafloor spreading toward mid-oceanic ridges where it is consumed. B)Oceanic crust continuously forms across the seafloor and is moved by subduction zones toward mid-oceanic ridges where it is consumed. C)Oceanic crust continuously forms at mid-oceanic ridges, moves away from these ridges by seafloor spreading, and is consumed at subduction zones. D)Earth's molten core material erupts at mid-oceanic ridges, moves away from these ridges by seafloor spreading, and is consumed at subduction zones. E)Subduction zones force oceanic crust to spread across the seafloor before being consumed at a fault valley.
