Question

Quizplus · Accepted Answer

Glacial till is formed when glaciers move over land, picking up various sizes of rock, sediment, and soil. As the glacier melts and retreats, it drops this mix of material, creating a heterogeneous mixture of mineral debris. Glacial till is not sorted by flowing water or wind, nor is it typically found in glacial lakes.
