Answer the question based on the following text.

Question:


Mike wants to see how fast water can run while not depositing small particles. In order to avoid get the smaller particles deposited, Mike will need the water to be running quickly or slowly? 


Text:

The size of the eroded particles depends on the velocity of the water. Eventually, the water deposits the materials. As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited.
