Which outcome accelerates glacial ice advance when basal debris concentrates?

💡 Explanation

Increased debris concentration at the glacier's base leads to enhanced basal sliding because Regelation causes meltwater films to facilitate ice movement over uneven surfaces; therefore, forward motion increases, rather than abrasion decreasing which is a different process.
