No matter what causes the rock to break, we call the smaller pieces sediment.

Water, wind, and gravity are the main processes that move pieces of rock from place to place. Sediment might get transported thousands of miles by one of the world's major rivers, or it might just go from the top of the hill to the bottom during a landslide or as a result of natural creep.
