The shape of a delta is primarily determined by ________.
A)the shape of the river channel near the mouth

C)whether river currents,wave-driven currents,or tidal currents are locally predominant
D)the type of rock that is weathering at the outcrop near the headwaters of the river

Question

Quizplus · Accepted Answer

The shape of a delta is primarily determined by the dominant type of water currents in the area, which can include river currents, wave-driven currents, or tidal currents. The interplay between these currents and the sediment load carried by the river will determine the characteristic shape of the delta. The other choices may also have some influence, but are not as significant in shaping the overall morphology of the delta.
