Answer:
Erosion
Weathering
Deposition
Explanation:
Erosion is the natural part of the rock. Sediments will not be there without erosion or the sedimentary rock. Therefore erosion is the picking of the unconsolidated soil as well as sediments. Most rivers erode to transport the sediments. The sediments in other places deposit the sediment in different locations. The principles agent behind the eroding bedrocks and sediments is the moving water.
The dissolving and worn of the rock is called weathering. Weathering occurred in different processes such as mechanical, organic and chemical processes.
