Sediments of various sizes are carried at the base of glaciers and deposited as poorly sorted _____.

Question

Quizplus · Accepted Answer

Sediments carried at the base of glaciers are called basal till or glacial till. Glacial till is poorly sorted and unstratified, meaning that particles of varying sizes and shapes are mixed together without any distinct layering or sorting by size. Glacial drift is a general term that refers to any sediment deposited by glaciers, including both till and stratified drift (which is sorted by size and shape). Moraines are ridges or mounds of till that are deposited along the edges or at the terminus of a glacier. So, the best choice is C- glacial till.
