← GeographyWhich outcome is caused by increased rates of longshore drift carrying sediment past a headland composed of chalk bedrock?
A)Increased sea stack formation downstream✓
B)Strengthened nearshore depositional features
C)Decreased wave refraction around headland
D)Reinforced offshore coastal sandbars
💡 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.
