The ocean floor is thus pushed at right angles and in opposite directions away from the crests. Showed altering bands on of normal and reversed polarity. Magnetic patterns are symmetrical on each side of the mid ocean ridge which would indicate that the seafloor is spreading apart like the tectonic plate theory claims.
