What would be the changes to ocean water movement if either the water temperature decreased or the salinity of the water increased? A: The water would rise causing water displacement and deep water currents would flow

B: There is no effect on the ocean water when either temperature or salinity changes

C :The water would sink causing water displacement and deep water currents would flow.

D: The water would flow in a northeast direction causing a current such as the Gulf Stream
