← GeographyWhich outcome is accelerated when rising ocean acidity affects nearshore sea stack formations composed of calcium carbonate?
A)Increased wave-base erosion rate✓
B)Progradation of associated barrier islands
C)Enhanced aeolian sediment transport
D)Decreased thermohaline circulation intensity
💡 Explanation
Increased wave-base erosion of sea stacks occurs because ocean acidification increases chemical weathering rate; this dissolution via carbonic acid weakens structure. Therefore, rocks succumb quicker to mechanical wave action, rather than the island accreting sediments.
