a glacier
The process of picking up and moving rocks is called rock lifting or rock relocation.
The scratch marks on rocks left by moving glaciers are called glacial striations. These marks are typically parallel and indicate the direction in which the glacier was moving.
River beds.
Very smooth rocks are called "polished rocks" or "river rocks" due to the smooth texture achieved from erosion in water bodies like rivers and oceans.
Moving water can weather rocks through a process called abrasion, where the water carries sediment that physically rubs against the rock, wearing it down. Chemical weathering can also occur as the water interacts with minerals in the rock, causing them to dissolve or break down. Over time, these processes can shape and erode the rock, changing its appearance.

material that a river carries along E.g (stone, grass & rocks)
Sediment load
Erosion-is the carrying small particles and other solids. (dirt, leaves, rocks and other particles)

the river current slows down it drops of rocks and gets some dissolved materal it carries on down the river two a shore
A fast moving river will. This is true because in a fast moving river more sediment is picked up from theedges of the stream and the bed making the riverwider and deeper. Also more rocks will be picked up eroding the other rocks.In a slow moving river less sediment will be picked up, and the river will erode slower.Therefor the river will also pick up less rocks and or smaller rocksthat wont erode the river as fast.
A river creates a canyon through erosion. The faster the water is moving the faster the canyon is going to be formed. The water rushes on the bottom and moves rocks as it goes along and the rocks scrape on other rocks and loosen up the soil and other rocks so it carves out a canyon.

sediment
deposition
water in a river is constantly moving. Moving water will pick up sediments from the bottom of a river, and carry them with it. Water also has the power to move large rocks slowly along the bottom of a river.
