Question

Quizplus · Accepted Answer

Stratified or sorted glacial sediment indicates that it was deposited by glacial meltwater. As the glacier melts, water carries sediment from the glacier and deposits it in layers, often sorting the sediment by size. Terminal moraines (A), medial moraines (D), and till (C) are all forms of unsorted glacial sediment, while sediment carried on top of the glacier (E) would not be stratified or sorted.
