Task: Explanation
Input (English): Question: If Mona is rafting on a river and the river is moving quickly, what happens to the size of particles that river deposits if the water slows down? 
 Answer: increases
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.
