Which term describes a long stretch of coastline that acts as a sediment-management unit with connected beaches and headlands?

• A. Beach
• B. Delta
• C. Coastal Cell
• D. Coral Reef

Answer: (C)

A coastal cell is a long stretch of coastline that acts as a sediment-management unit with connected beaches and headlands. Within a cell, sediment is moved mainly alongshore by longshore drift, and the boundaries—often headlands or engineered structures—limit exchange with neighboring sections. This framing helps explain how erosion and deposition occur across a linked set of beaches and why actions in one part of the coast can affect adjacent areas. The other terms describe individual features rather than a linked sediment system: a beach is just a single landform, a delta forms at a river mouth, and a coral reef is a biological structure.
