Which outcome results when glacial outwash undergoes sorting?

A)Stratified drift sediment deposition
B)Formation of ablation till deposits
C)Development of esker landforms
D)Generation of unsorted glacial erratics

💡 Explanation

Stratified drift happens because meltwater sorts sediment by particle size during deposition, a process called hydraulic sorting effects. This results in distinct layers of sediment of uniform size, therefore a stratified drift deposit is created, rather than unsorted till.
