The shape of a delta is primarily determined by ____________.
A)the shape of the river channel near the mouth
B)the average grain size of the suspended and bed loads
C)whether river currents,wave-driven currents,or tidal currents are locally predominant
D)the type of rock that is weathering at outcrop near the headwaters of the river

Question

Quizplus · Accepted Answer

The shape of a delta is primarily determined by the dominant currents near the mouth of the river, whether they are river currents, wave-driven currents, or tidal currents. These currents determine the distribution of sediment deposited at the mouth of the river, which ultimately shapes the delta. Factors like the shape of the river channel near the mouth and the average grain size of the sediment may also play a role, but are secondary to the influence of the dominant currents. The type of rock weathering at the headwaters is not directly related to the shape of the delta.
