Which feature forms when a shrinking glacier deposits sediment at the downstream margin of a cirque?

💡 Explanation

When a glacier retreats within a cirque, the glacier deposits material called till at its furthest extent. Over time, subsequent debris deposits gradually form a mound called a Terminal Moraine Dam, raising water levels behind it to create a lake. Therefore, the terminal moraine dam forms, since kame, esker, and drumlin are from outwash plain environments.
