← GeographyWhich mechanism causes stack formation accelerating after wave refraction?
A)Differential wave energy focusing✓
B)Isostatic subsidence increasing erosion
C)Aeolian sediment deposition rate
D)Halocline formation inhibits mixing
💡 Explanation
Stacks experience focused wave energy via wave refraction; wave energy converges on their bases causing increased erosion due to differential wave energy focusing because they disrupt normal wave patterns. Therefore, accelerated erosion enhances stack formation, rather than other factors.
