Which landform is a deep, glacially carved inlet with high, steep walls or valleys?

• A. Foreshore
• B. Estuary
• C. Fjord
• D. Drumlin

Answer: (C)

Glacially carved inlets that are deep and bounded by high, steep walls are fjords. They form when a valley carved by a glacier becomes flooded by seawater as the glacier retreats, leaving behind a deeply recessed, U-shaped valley with dramatic, cliff-like sides. This contrasts with an estuary, which is the tidal, mixing zone at a river mouth and is not a carved glacial feature; a foreshore is simply the coastal area between high and low tides; and a drumlin is a smooth, elongated hill created by glacial deposition, not a kind of inlet. Fjords are classic examples of glacial erosion creating deep, rugged coastlines.
