Which term describes a long stretch of coastline that acts as a sediment-management unit with connected beaches and headlands?
Correct Answer:
Coastal Cell
Explanation:
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.
