      As a glacier flows it picks up and transports a huge load of debris.Eventually, all this material will be deposited once the ice melts.Drift is the term used for all sediments of glacial origin, no matter how, where, or in what form they were deposited.There are two distinct types of glacial drift: till and stratified drift.Till is the material that is deposited directly by the glacier.Stratified drift is the sediment laid down by glacial melt water.The main difference between till and stratified drift is that ice cannot sort the sediment it carries, hence till is composed of unsorted particle sizes.Stratified drift is sorted according to the size and weight of its fragments.
