Which landform is an elongated hill of glacial material deposited parallel to glacial movement?

• A. Drumlin
• B. Eustatic Change
• C. Fjord
• D. Estuary

Answer: (A)

Drumlins are elongated hills of glacial till that form and align in the direction of ice movement. Their streamlined shape, with a blunt end facing the oncoming glacier and a tapered end downstream, records the flow direction of the ice. They arise from how sediment is deposited beneath or at the base of a moving glacier as it lodges and reshapes material, creating smooth, parallel ridges over a landscape once covered by ice. The other terms describe different glacial or coastal features not formed as elongated hills of deposited material: a fjord is a glacially carved valley flooded by seawater, an estuary is a river mouth where freshwater mixes with seawater, and eustatic change refers to global sea level changes, not a landform.
