Deep water masses encountering mid-ocean ridges go up and over the features, forming new oceanic crust through seafloor spreading.
When deep water masses encounter ocean floor features such as mid-ocean ridges, they go up and over the features. The ridges, also known as spreading centers, create new oceanic lithosphere through seafloor spreading, forming new oceanic crust. This process influences ocean circulation by separating deep waters into distinct basins and creating turbulence.
