Which mechanism causes increased ocean atmospheric CO2 absorption during coastal upwelling events?

💡 Explanation

During upwelling, nutrient-rich deep water rises, fueling phytoplankton blooms; photosynthesis then converts CO2 into organic matter, which settles to the ocean floor upon their death, effectively sequestering it. Therefore, increased CO2 absorption results, rather than other options which affect other separate mechanisms on the ocean.

• Which process accelerates the lateral migration of a river's meander across an alluvial plain landscape?
• Which outcome occurs when a barrier island migrates landward?
• Which outcome arises where a low-gradient river encounters localized bank erosion during flood conditions?
• Which process causes terraced landscapes within an alluvial river valley environment?
• Which feedback arises when increased rainfall rapidly saturates soluble bedrock, forming new sinkholes?
• Which mechanism causes the formation of lobate landforms associated with solifluction on Arctic slopes?
