What is the primary driving force behind ocean currents?

  1. Wind

  2. Earth's rotation

  3. Density differences

  4. Tides


Correct Option: A
Explanation:

Wind is the primary driving force behind ocean currents. The wind transfers its energy to the ocean surface, causing water to move in the direction of the wind.
