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.
