Question

Quizplus · Accepted Answer

End or ground moraines formed by a continental ice sheet are most useful for tracing kimberlite cobbles and minerals directly to their bedrock source area because these deposits are left directly by the melting ice, often in a broad swath that can directly trace back to the source area, unlike the more localized or specific conditions required for the formation of lateral or medial moraines, kames, and kame terraces.
