Answer: The statement is True.
Step-by-step explanation:
Ocean mass is constantly shifted and mixed by more or less rapid movements, caused by the interference of two fundamental mechanisms: winds and density differences, whose origin lies in the contact surface between the atmosphere and the sea. The movements of the deep mass of the oceans, despite their slowness, are also current, since they drag the water in a defined direction. This movement is due to density differences, which in turn depends on temperature and salinity.
