Which phenomenon causes deflection of large-scale ocean currents influencing global heat distribution through the Coriolis effect?

A)Gyre formation along continental coastlines
B)Thermohaline circulation in polar regions
C)El Niño events altering trade winds
D)Upwelling zones promoting phytoplankton blooms

💡 Explanation

When the Earth rotates, the Coriolis effect deflects moving objects relative to the surface of the Earth because of inertia and spherical geometry, leading to large-scale circulation. Therefore gyre formation results, rather than thermohaline circulation, El Niño, or upwelling which depend on thermal or wind patterns.
