Final answer:
Long, sinuous ridges of stratified drift associated with continental glaciation are called eskers, which are formed from glacial meltwater streams depositing into subglacial tunnels.
Step-by-step explanation:
Long, sinuous ridges of stratified drift associated with continental glaciation are called eskers. These features are formed under glaciers where meltwater streams deposit sand and gravel into subglacial tunnels. As the glacier retreats, these tunnel fillings remain as long, winding ridges that reveal the path of the meltwater streams beneath the former ice sheet. In contrast, moraines are accumulations of debris directly deposited by a glacier, drumlins are smooth, elongated hills of unsorted glacial deposits, and kames are irregularly shaped hills or mounds composed of sand and gravel.
