Which outcome of glacial movement increases when ice streams surge?

💡 Explanation

An ice stream surge accelerates sediment detachment via basal sliding, therefore deposition increases because the sediment drift formation rate rises along marginal moraines rather than cryoconite spread rates increasing or esker formation diminishing.
