erosion of the stream bank deposition of material in the stream amount of material carried downstream size of the particles carried downstream
I gave my students this multiple choice question: As stream velocity decreases, which factor will likely increase?

Only one answer is correct among these 4 choices:
- erosion of the stream bank
- deposition of material in the stream
- amount of material carried downstream
- size of the particles carried downstream

Could you tell me which one is correct?

deposition of material in the stream
