Sediments move downstream through processes like erosion, transportation, and deposition by the force of water, wind, or ice. As water flows, it picks up and carries sediments, gradually depositing them as the energy of the water decreases. This continuous cycle of erosion, transportation, and deposition allows sediments to be transported downstream over time.
Sediments are small particles of soil or rocks that are transported by water or wind. They can vary in size from tiny clay particles to larger sand or gravel particles. Sediments can be carried downstream by rivers or blown by the wind to new locations where they may eventually settle and accumulate.
Sediments in sedimentary rock can be transported by wind, water, or glaciers
Gold can be eroded from mineral deposits by flowing water and transported downstream, where it settles in the riverbed sediments due to its high density. Over time, sedimentation processes bury the gold particles in layers of sediment along with other minerals and rocks.
Stream transport sediment in three ways, dissolved load, (ions in solution being carried downstream), suspended load, (suspended sediment that floats freely downstream) and bed load, (sediment that rolls or scoots along the bottom of the river).
Frost heaving is the mass movement that occurs when sediments freeze and thaw. During freezing, water in the sediments expands as it turns to ice, pushing particles upwards. When the ice thaws, the sediments settle back down, causing the surface to move vertically over time.
How do sediment move
As water moves downstream, it can transfer sediments, nutrients, pollutants, and organisms. This movement of materials and organisms can affect downstream ecosystems and water quality.
Erosion wears away sediments deposition, typically through the action of water, wind, or ice. These erosional forces transport sediments from one place to another, carrying them downstream or depositing them in new locations.
Water, wind, gravity, and ice can all move sediments from one place to another.
umm erosion?
The force that is responsible for moving sediments in a river is the current.
The process in which sediments move slowly downhill, is called creep. It is common where freezing and thawing occur. As ice expands in soil, it pushed sediments up. Then as soil thaws, the sediments move farther downslope. Over time, creep can move large amounts of sediment, possibly causing damage to some structures
The land between and around rivers, e.g. in the flood plains and deltas, is full of sediments and nutrients that were carried downstream.
The rocks will gradually get smaller

The second image shows sediments in motion. The movement is likely caused by the flow of water or the force of gravity on the slope where the sediments are located.
