← GeographyWhich phenomenon results, when surface winds approach continental coasts transversally in Northern Hemisphere?
A)Ekman transport and coastal upwelling✓
B)Geostrophic balance and density changes
C)Evaporation rates and surface salinity
D)Adiabatic cooling and cloud condensation
💡 Explanation
Ekman transport occurs because the Coriolis effect deflects surface currents 45° from wind direction; therefore, coastal upwelling results along the coast rather than downwelling, which would occur if currents were aligned because of negligible coriolis forces rather than significant differences.
