In the past, glaciers have covered more than one third of Earth's surface, and they continue to flow and to shape features in many places. Streamflow characteristics at gaging stations were related by multiple regression techniques to basin and climatic characteristics and equations were developed for estimating streamflow characteristics at ungaged sites. A major problem for previous genetic classifications has been that glacial deposition and the resulting deposits properties were poorly understood. - warm currents may either inhibit or increase glaciation. Glacial till is angular where fluvioglacial deposits are sub The characteristic of most glacial deposits is that they are a.) Till or glacial till is unsorted glacial sediment.. Till is derived from the erosion and entrainment of material by the moving ice of a glacier.It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines..
