Which outcome will accelerate glacial retreat when volcanic ash deposits darken ice surfaces?

💡 Explanation

Enhanced radiation occurs with increased absorption, because the tephra causes increased radiative forcing, heating glaciers, increasing melting, which is ablation. Therefore, enhanced ablation accelerates glacier retreat, rather than precipitation or albedo effects.
