Which outcome results when glacial meltwater encounters impermeable ground, depositing sediments?

💡 Explanation

Esker deposition occurs because subglacial streams deposit sediments as meltwater flow decreases on impermeable surfaces; therefore a sinuous ridge forms, rather than terminal moraines which form at the ice edge.
