Answer:
A. coriolis effect
Step-by-step explanation:
- The ocean water is affected by the Coriolis force of the earth in motion these forces are directed by the axial tilt and the revolution of the earth around the sun and hence creates the warm and the cold currents in motion.
- The impact of the Coriolis force thus makes the currents in the northern hemisphere direct to the anticlockwise direction and the clockwise direction in the southern hemisphere.
- Thereby affecting the ocean water density and the density of the place which depends on these factors of the land and the oceanic mass. And similarly, they regulate the flow of the temperature around the globe.
