Which ocean phenomenon results when offshore winds drive surface waters away from a coastline?

💡 Explanation

When offshore winds displace surface waters, upwelling occurs because deep, nutrient-rich water rises to replace the surface water, fuelling primary production. Therefore, increasing marine productivity results, rather than gyre formation, erosion or circulation changes, which depend on other mechanisms.

• Which pedogenic effect results more rapidly when alternating extreme temperatures cause repeated volumetric change in granite?
• Which risk increases when a megathrust earthquake occurs along a subduction zone lacking strain partitioning?
• Which outcome is directly amplified when a coastal gyre weakens?
• Which outcome occurs when reduced atmospheric pressure differences weaken trade winds?
• Which outcome on South American fisheries occurs during an El Niño event, altering ocean currents?
