← GeographyWhich 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.
