← GeographyWhen coastal bedrock subsides following glacial retreat in fjords, which outcome is most probable?
A)Progressive isostatic rebound acceleration
B)Increased seawater intrusion extent✓
C)Enhanced sediment deposition rate
D)Decreased coastal erosion effects
💡 Explanation
Seawater intrusion increases because bedrock subsidence from decreased ice mass, following glacial isostatic adjustment involving depression and rebound, allows greater tidal influence; therefore, more saline water penetrates further inland, rather than uniform uplift.
