Deltas and caves. 😁
canyons and plateaus
Most sediment washes or falls into the river as a result of mass movement and runoff. Other sediment erodes from the bottom or sides of the river
When rocks and sediments are moved, erosion occurs, resulting in the formation of landforms such as hills, valleys, canyons, and deltas. Sediments can also accumulate to form new landforms like beaches and sand dunes.
Landforms such as mountains, plateaus, and volcanoes are not primarily formed by running water. These features are usually the result of tectonic forces, volcanic activity, or erosion by ice and wind.
The two main factors that affect how quickly a coastline erodes are wave energy and the type of rock or sediment present along the coast. Higher wave energy can result in more erosion, while softer rocks or sediments are more easily worn away compared to harder materials.
I'm afraid you've misunderstood sediment, and you can't concatenate two such different structures as you have. Sediment is deposited fragments of material sized from silt up to cobbles or boulders, resulting from weathering and erosion of any rock. Deltas are estuarine deposits of sediment transported suspended in the river, from erosion up-stream. Caves, or most of them anyway, do not result from erosion of sediments, but from the erosion by chemical weathering (dissolution) of sedimentary rock - specifically limestone - and the material is carried away in solution not suspension.
A river curves back and forth because it becomes wider then the river erodes land on one side and deposits sediments along the other side this causes the river to develop curves P.S. i'm 9!

Sedimentary rocks.
Deposition is the process where sediments, soil, or rocks are deposited by wind, water, or ice, creating new landforms such as beaches, sand dunes, or river deltas. Over time, deposition can contribute to the formation of sedimentary rocks through compaction and cementation.
Lithogenous sediments come from the land They result primarily from erosion by water, wind, and ice Biogenous sediments originate from organisms The particles in these sediments come from shells and hard skeletons. Although lithogenous sediments represent the largest total volume, biogenous sediments cover a greater area of sea floor
Sediments formed from seawater through various chemical processes are called chemical sediments or authigenic sediments. These sediments typically result from the precipitation of minerals as seawater evaporates or undergoes changes in temperature and salinity. Common examples include limestone, which forms from calcium carbonate, and evaporites such as gypsum and halite. These sediments play a significant role in marine geology and the formation of sedimentary rock.
