Which river process is most important in forming a delta?
Answer and explanation
Correct answer: Deposition
A delta is governed mainly by deposition at a river mouth. When a river enters a sea or lake, its gradient and velocity decrease, so it loses the ability to carry much of its sediment. The sediment accumulates and may form distributary channels and a triangular or fan-shaped delta. Thus option A is correct; the other choices involve evaporation, glaciers or wind.
