Which outcome occurs when housing development disrupts sediment supply to barrier islands?

💡 Explanation

Increased erosion of dunes occurs because reduced sediment replenishment bypasses natural coastal protection, the 'sediment budget'; therefore, frontal dunes degrade rather than migrating/expanding, which would require sediment input, and are unrelated salinity diffusion.

• Near a rocky headland, which outcome reduces beach area after prolonged storms?
• Which outcome follows reduced wave refraction around stacks?
• Increased monsoon intensity over uncultivated loess accelerates which outcome?
• Which landscape formation occurs because vegetation removal destabilizes dunes?
• Which risk increases when differential pressure forces magma into forming volcanic domes underneath a glacier?
• Which increased outcome is caused along artic slopes due to repeated freeze-thaw cycles acting together?
