... Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. As the time passes, the ocean floor spreads and extends. WHILE OCEANIC LITHOSPHERE IS CONSTANTLY BEING FORMED AT THE RIDGES, IT I ...

Physical oceanography
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters.Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanographies.
