What is the most precise difference between a river’s capacity and competence?
Answer and explanation
Correct answer: Capacity is the total amount of sediment a river can carry, whereas competence is the largest particle size it can move
In fluvial geomorphology, capacity refers to the total quantity of sediment that a stream can transport under given conditions. Competence refers specifically to the maximum diameter or weight of an individual particle that the stream can move. A high discharge may increase capacity, while high velocity and turbulence strongly affect competence. Option A states this distinction accurately; the remaining choices confuse dimensions, unrelated processes, or glacial deposits.
