Which consequence results when longshore drift is interrupted by a poorly sited harbor breakwater?

💡 Explanation

Interruption of sediment transport leads to sediment accumulation (accretion) on the up-drift side and sediment starvation (erosion) down-drift because longshore drift normally supplies this sediment; therefore, the correct answer is A, rather than uniform distribution or other wave effects in options B, C, and D because of the disruption.

• Which mechanism causes increased slumping when stacks collapse?
• Which erosion outcome primarily results when exposed granite undergoes chemical alteration?
• Which landscape outcome occurs when intense wind deflation acts on unconsolidated sediments?
• Which effect increases as plastic debris accumulates in ocean gyres experiencing stratification?
• Which outcome occurs when freshwater influx disrupts circulation?
• Which outcome occurs when sediment discharge surpasses capacity at canyon mouths?
