Which outcome is caused by increased rates of longshore drift carrying sediment past a headland composed of chalk bedrock?

💡 Explanation

Increased sediment transport through longshore drift, due to significant chalk erosion, causes increased sea stack formation downstream because material removed from the headland is deposited offshore leading to formation of stacks, rather than accretion of mainland beaches.
