Which outcome occurs when nearshore wave refraction diminishes along a coastline exhibiting longshore drift?

💡 Explanation

Decreased wave refraction reduces wave energy, which results in less sediment mobilization via longshore drift; therefore, sand supply decreases downdrift because sediment transport is impaired, rather than increasing deposition upgradient or affecting thermal stratification.

• Which process significantly weakens the Atlantic Meridional Overturning Circulation (AMOC) when Arctic ice melt accelerates?
• Which risk intensifies as alluvial river plains subside?
• Which risk increases when rapid groundwater extraction lowers the water table within a soluble bedrock formation containing existing sinkholes?
• Which outcome occurs when magma buoyancy exceeds lithospheric strength?
• Which risk increases because internal pressure is confined when magma domes block volcanic vents following an eruption?
• Which outcome increases when highly soluble bedrock groundwater withdrawal exceeds recharge?
