A long, winding ridge of stratified sand and gravel is known as:
esker
The correct answer is esker.
Compared to other glacial features: Unlike drumlins or moraines, which are typically composed of unsorted till (sediment deposited directly by ice), eskers are made of stratified sand and gravel because they are deposited by flowing water, which sorts sediment. Kames are also made of stratified sand and gravel but are typically more irregular mounds or hills, formed in different depositional environments related to melting ice. Therefore, the unique combination of being a long, winding ridge and being composed of stratified sand and gravel distinctly identifies this landform as an esker.
