What causes gyres?
A. deep currents
B. the Coriolis effect
C. the Equatorial countercurrent
D. West Wind drift
Answer (1)
Gyres are primarily caused by the Coriolis effect, which results from Earth's rotation, leading to the deflection of ocean currents. This effect shapes large, rotating systems of currents known as gyres. Other factors, like deep currents and specific ocean currents, contribute to ocean circulation but do not cause gyres directly. ;
