Yes, it is a standard feature of passive continental margins (like the Atlantic). It is less pronounced or absent at active margins (like the Pacific 'Ring of Fire') where trenches are present.
It contains a historical record of sediment from the continent, is a potential site for deep-sea mineral resources, and influences deep-ocean current patterns.
