← GeographyWhich surface salinity change occurs because El Niño?
A)Reduced upwelling causes lower salinity✓
B)Increased ice melt dilutes ocean water
C)Enhanced evaporation raises ocean salinity
D)Reduced river discharge increases salinity
💡 Explanation
El Niño reduces coastal upwelling, lessening the transport of deep, salty water; therefore, surface salinity decreases because decreased upwelling dominates, rather than ice melt or evaporation affecting only specific regions.
