Which outcome occurs in coastal ecosystems when persistent offshore winds drive significant upwelling events?

💡 Explanation

When strong offshore winds promote upwelling, nutrient-rich water from the deep ocean rises because the surface water is displaced, boosting phytoplankton growth, but sometimes species produce harmful algal blooms. Therefore rapid HAB expansion results, rather than acceleration acidification, methane release or canyon erosion, which require different processes.

• Which outcome occurs when irrigation in arid climates mobilizes soluble salts?
• Which process degrades lagoon habitat behind barrier islands?
• Which risk increases when upstream river engineering projects disrupt sediment deposition in floodplains adjacent to engineered levees?
• Which mechanism causes fjord sill formation at the mouth of a glacial valley?
• Which process causes subsidence on the downthrown side of a growing normal fault?
