The correct option is To the right in the northern hemisphere..
Explanation
The Coriolis force is an apparent force caused by the rotation of the Earth on its axis. It plays a critical role in determining the direction of movement for ocean currents and winds globally. This force is zero at the equator and increases towards the poles.
Analysis of Deflection
- Northern Hemisphere: Due to the Earth's rotation from west to east, the Coriolis force deflects moving objects, including ocean water, to the right of their path of motion. Therefore, warm currents moving from low latitudes (equator) towards higher latitudes are deflected to the right.
- Southern Hemisphere: In the Southern Hemisphere, the Coriolis force deflects moving objects to the left of their path of motion.
- Resultant Movement: Consequently, ocean currents do not flow in a straight line from the equator to the poles but follow curved paths, contributing to the formation of large circular current systems known as gyres.
Key Takeaway: Under the influence of the Coriolis force, ocean currents are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere (Ferrel’s Law).
