Which characteristic indicates the equilibrium line altitude lowering on a cirque glacier?

💡 Explanation

When the equilibrium line lowers, net accumulation decreases and net ablation increases because the meltwater runoff increases significantly, leading to a proglacial lake expansion. Therefore, a larger proglacial lake forms, rather than increased horn formation, bergschrund formation, or elevated trimline which result from other glacial processes.
