Which process increases when glacial meltwater stream volume increases?

A)Isostatic rebound
B)River terrace formation
C)Cryoconite hole formation
D)Subglacial lake drainage

💡 Explanation

An increased meltwater stream volume causes greater erosion decreasing the ice sheet mass; isostatic rebound arises because reduced weight allows the underlying bedrock to rise. This uplift overwhelms glacial erosion, therefore, isostatic rebound increases rather than the other processes tied to the stream itself.
