Which of the following depositional features in a glacial environment consists of winding, steep-sided ridges of stratified sand and gravel deposited by meltwater streams flowing within or under glaciers?

💡 Solution & Explanation

Eskers form as long, winding ridges composed of stratified sand and gravel deposited by meltwater streams flowing through ice tunnels within or beneath stagnant glaciers. Unlike drumlins which are streamlined hills of till, eskers specifically reflect glacial drainage patterns.
