Question

Describe the "clock" direction of surface currents in the northern hemisphere. 2. describe the "clock" direction of surface currents in the southern hemisphere. 3. what is the most common source of energy for surface currents? 4. what is the relationship between the movement of the atmosphere and the movement of surface currents?

Answer 1

- The currents flow in certain patterns through the world.

- The currents in the northern hemisphere flow clockwise up from the equator toward the polar regions and then back.

- While the currents in the southern hemisphere flow in a counterclockwise direction south from the equator to the polar regions.

- Surface water cooled in the polar region. Near the poles, the surface water is cooled and becomes heavier. This cool, heavy water sinks and flows towards the equator. Along the way, it mixes with warmer, fresh water and gradually rises. eventually, the surface waters are moved by the winds toward the polar regions to complete the cycle. 

- The surface current is driven by wind and follow global atmospheric patterns. Cold surface currents move from the polar regions to the equatorial zones, and warm surface current moves in opposite way.
