← GeographyWhich outcome occurs when glacial meltwater decelerates sharply?
A)Esker deposition along former meltwater channels✓
B)Cirque formation through glacial plucking
C)Frost shattering via ice expansion
D)Formation of ventifacts via aeolian abrasion
💡 Explanation
Esker deposition occurs because decreased velocity reduces the water's sediment transport capacity; therefore, sorted sediments are deposited. The mechanism is settling, rather than glacial erosion, frost shattering, or wind abrasion.
