Question

Quizplus · Accepted Answer

Ocean currents are primarily driven by wind patterns and the shapes of land masses, which can affect the direction and strength of the currents. Factors such as air temperature, rainfall, animal activity, and runoff can also have some influence on currents, but they are not the most significant factors.
