Under which condition does a bird-foot delta form?
Answer and explanation
Correct answer: When river deposition is stronger than marine reworking and distributaries extend seaward
A bird-foot delta forms when a river carries abundant sediment and its deposition dominates the opposing action of waves, tides, and coastal currents. The river channel splits into long, narrow distributaries that project seaward like the toes of a bird. Option C is correct because it states both the controlling balance of processes and the resulting distributary pattern. The other choices cannot create this river-dominated delta.
