← GeographyWhich outcome occurs when a coastal cliff's base erodes?
A)Cliff destabilization and slope retreat✓
B)Increased sediment deposition offshore
C)Formation of a stable beach terrace
D)Accelerated coral reef development
💡 Explanation
Cliff destabilization and slope retreat occurs. Undercutting leads to a loss of support; therefore, the overhanging cliff collapses through mass wasting, rather than producing deposition or reef growth, because support removal dominates.
