Which reef forms directly along the coastline in shallow tropical waters, often extending from the shore?

• A. Fjord
• B. Estuary
• C. Fringing Reef
• D. Drumlin

Answer: (C)

Fringing reefs grow directly along the coastline in shallow tropical waters, often extending right from the shore. They form where warm, clear seawater near the sunlit surface supports coral growth close to land, producing a narrow reef belt that hugs the coast and may have little or no lagoon between reef and shore. The other options don’t fit this coastal, shallow-water pattern: fjords are glacially carved, deep valleys filled with seawater; estuaries are tidal river mouths where freshwater mixes with seawater; drumlins are elongated hills formed by glacial movement.
