Question

]In your own words, explain how the changes in the density of ocean water causes movement of ocean water from one place to another.

Answer 1

In my opinion, if the density of the ocean water increase, D=m/V, let d mass be constant, the volume of H2O might be decreasing. Therefore volume will be the same as concentration of water. The water will flow from higher to lower concentration of water region in terms of con;for example the region of low density will flow to high density region. This is my idea and not the actual answer.
