Which consequence results when wave refraction weakens coastal sea stacks?

💡 Explanation

Wave refraction concentrates energy on headlands but disperses it in bays; therefore stacks erode non-uniformly, leading to collapse that feeds sediment into the longshore transport system, because the sediment source increases, rather than offshore island formation, crystal growth, or upwelling.

• Which outcome decreases island size when wave diffraction occurs?
• Which outcome occurs when earthworm populations decline drastically?
• Which long-term consequence results from extensive wave focusing during coastal storms?
• In Arctic regions, which of these increases risk for building foundations placed on permafrost soils?
• Which outcome results when increased chemical weathering alters the underlying rock during pedogenesis?
• Which risk escalates when human-constructed levees significantly constrain a deltaic river's natural floodplain?
