Which effect results when persistent ice dams form along glacial meltwater streams?

💡 Explanation

Albedo changes occur, because ice dams increase surface reflectivity causing localized cooling via the albedo feedback mechanism. Metamorphism requires pressure/temperature; methane release is limited; chemical weathering is too slow; therefore albedo is greater, rather than mineral alteration.

• Which risk increases when coastal sediment transport stops due to a dam interrupting longshore drift?
• Which outcome accelerates continental nutrient depletion via aeolian processes?
• Which outcome increases near coastal freshwater streams during regional saltwater intrusion events?
• Which effect is directly enhanced by increased upwelling along a coastline?
• Which mechanism causes density-driven ocean circulation when surface water salinity increases substantially at high latitudes?
