← GeographyWhich mechanism accelerates coastline retreat when storm surge impacts uncompacted sediments?
A)Hydraulic scour erodes base✓
B)Isostatic rebound compacts soils
C)Halocline intrusion stabilizes bluff
D)Aeolian deposition builds dunes
💡 Explanation
Hydraulic scour causes rapid erosion as surge over-steepens the beach profile. Intense wave action undercuts the base because unconsolidated materials are easily dislodged; therefore, the coastline retreats. Rather than other options, scour is the primary erosion mechanism during storm events.
