Which consequence results when eustatic sea level rises rapidly behind a coastal barrier island system?

💡 Explanation

Increased flooding and breaching occur because the **rollback mechanism** causes rapid landward migration of the barrier; therefore, overwash increases rather than habitat stabilizing, due to barrier instability and drowning.

• Which hazard results because unconfined pyroclastic density currents from a collapsed eruption column encounter topographic constraints?
• Which outcome occurs when nearshore sand dunes erode?
• Which consequence results when destabilization occurs due to solifluction?
• Which outcome occurs in a delta region when artificial levees prevent seasonal flooding?
• Which geological change results when acidic rainwater interacts with fractured limestone?
• Which mechanism reduces primary productivity in the eastern Pacific Ocean during an El Niño event?
