A RELATIVE plate velocity can be determined looking at the ages of the oceanic crust and its distance from the mid ocean ridge. We call this “relative motion” because both plates on either side of the mid ocean ridge are movin ...

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.
