The correct statements regarding the role of the Coriolis effect on ocean currents are:
- The Coriolis effect turns currents counterclockwise in the Northern Hemisphere.
- The Coriolis effect turns currents clockwise in the Southern Hemisphere.
Additionally, the Coriolis effect turns wind to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
So, the first two responses regarding ocean currents are the main points, but it would be beneficial to clarify that the wind is affected in a similar manner, just in different contexts.
