Task: Explanation
Input (English): Question: Mike wants to see how fast water can run while still depositing small particles. In order to get the smallest particles deposited, Mike will need the water to be running 
 Answer: slowly
Output (English): 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.
