Which outcome occurs when a cirque glacier experiences increased basal sliding?

💡 Explanation

Increased basal sliding enhances bedrock erosion and cirque deepening by regelation, because increased water at the base melts and refreezes around bedrock protrusions promoting fracture; therefore, bergschrund crevasses increase, rather than promoting arêtes or reduced weathering.
