When coastal bedrock subsides following glacial retreat in fjords, which outcome is most probable?

💡 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.

• Which risk increases when soil consolidation inhibits bioturbation?
• Which perturbation arises during strong El Niño phases?
• Which consequence occurs when an alluvial aquifer collapses?
• Which risk increases within flood control channels constructed atop karst bedrock regions?
• Which risk increases when a coastal development alters surface runoff patterns near an oceanic gyre?
• Which outcome occurs when surface soil acidity increases above karst bedrock?
