The answer is
When water loses its ability to hold sediment due to a decrease in velocity or capacity, it deposits the sediments it was carrying. This process is called sedimentation, and it can result in the formation of sedimentary layers over time.
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.
Alluvial fans form where water moving fast (a high energy state) and therefore carrying a lot of sediment of various sizes suddenly slows down (a low energy state) and therefore dumps most of the load it is carrying. They therefore develop where streams issue from canyons onto an adjacent valley floors.
Liquid and ice. Ice causes mechanical wedging that breaks up larger rocks until they are small enough to be removed from the source area by rushing water and deposited in a lower-energy environment.
A landform created when a river reaches a large body of water and deposits sediments is called a delta. Deltas are typically triangular or fan-shaped and form where the river's velocity decreases, causing it to deposit the sediments it has been carrying.
The sediments build up on the floor of the stream, ocean, river, or lake and causes the water to lower.
sediments left behind by moving water or wind
Wind or water carrying sediment deposits its load in slow moving or standing water. Sediment typically comes from beaches, erosion, and typical weathering.
By weathering rock and carrying it away to different places. That process is called erosion. Then it deposits the sediments and builds, which is called deposition.

A fast-moving water carries more sediments because it has more energy to erode and transport particles. Slow-moving water has less energy and is typically not able to carry as much sediment.
Fine sediments like silt and clay tend to stay suspended in moving water because the turbulence keeps them from settling. Coarser sediments like sand and gravel require calmer conditions to settle out of the water column.
deposition
When gravity and friction overcome the ability of the moving water to move them.
Sediments at beaches are usually rounded and smooth due to the continuous action of waves and currents moving them back and forth along the shoreline. This process, known as abrasion, wears down sharp edges and irregularities on the particles, resulting in their rounded and smooth appearance.
Marine life and oxygen for those organisms to survive ! And sediments, which are none living !
