Question: If the rate of flow in a river were reduced, what would happen to the size of sediment particles being deposited on the riverbed?
Option1: smaller particles would be deposited
Option2: larger particles would be deposited
Explanation: 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.

Ex Output:
smaller particles would be deposited
