Which phenomenon results from the Coriolis effect deflecting Northern Hemisphere surface currents?

A)Upwelling along western continental coasts
B)Equatorial temperature inversions formation
C)Deep ocean current saline intensification
D)Thermocline layer depth homogenization

💡 Explanation

When wind-driven surface currents encounter a continental boundary, the Coriolis effect deflects water to the right in the Northern Hemisphere because the Earth's rotation alters apparent direction, generating offshore Ekman transport that causes nutrient-rich, deep water upwelling along west coasts. Upwelling is thus caused, rather than temperature inversion, saline differences or homogenization, which require different atmospheric dynamics.
