← GeographyWhich outcome is amplified downwind when coastal upwelling occurs?
A)Thermocline gradient intensifies offshore✓
B)Dissolved oxygen levels decline nearshore
C)Fog formation decreases inland
D)Salinity fluctuations stabilize nearshore
💡 Explanation
A stronger thermocline gradient intensifies offshore because Ekman transport displaces surface waters, which enhances subsurface upwelling; therefore, offshore gradients increase, rather than conditions near shores which exhibit varied and minimal changes due to surface mixing.
