The ocean feature that is directly related to seafloor spreading is mid-ocean ridges. Mid-ocean ridges are underwater mountain ranges formed by tectonic plates pulling apart, creating new oceanic crust as magma rises from below the Earth's mantle. This process is a key aspect of seafloor spreading.
