They erode by transporting material ranging in size from microscopic to larger than a house, from one place to another place. Transportation occurs mainly because of the downward gradient of flowing water, which is attributable to the force of gravity.

The largest sediments are rolled along the bottom of the river. Some are small enought to bounce along the bottom. Smaller sediments can be carried in suspension, and some can be dissolved in the water. Sediments eroded by rivers are often very round and smooth. The longer the sediment was carried by the river, the rounder, smoother, and smaller it would be.
