In which condition does a bird-foot delta develop better?
Answer and explanation
Correct answer: River deposition exceeds marine reworking and distributaries extend seaward
A bird-foot delta develops where a sediment-rich river builds long, narrow distributaries outward into relatively quiet coastal water. River deposition must exceed the ability of waves, tides, and currents to redistribute the sediment laterally. The distributaries then project like toes, producing the characteristic shape. High wave energy or little sediment would destroy this pattern, so option D is correct.
