Hydrologically some geologic basins are both above and below sea level such the Maracaibo Venezuela although geologically it is not considered oceanic because continental shelf underlain by crust. Thus for each segment of new ocean floor created the ridges equal amount old oceanic crust is destroyed trenches socalled subduction zones. features that are less than feet high the bottom flanks of oceanic ridges [...]
