Which consequence develops as substantial tephra deposits accumulate in glaciated valleys?

💡 Explanation

Increased tephra accumulation on glacier surfaces lowers albedo, causing increased absorption of solar radiation and triggering ablation because the increased absorption overwhelms the cooling effect of the ice, rather than stabilizing permafrost, therefore ice melts faster.
