Sediment
Its deposits sediment by picking the sediment up which is called plucking.(weathering)
Wind transported sediment is known as "aeolian sediment."
No, fan-shaped deposits of sediment are called alluvial fans. Floodplains are flat areas next to rivers that are covered in sediment during floods.
That is called a delta. Deltas form when sediment carried by the river is deposited due to reduced water flow or when it meets another body of water, causing the sediment to settle and accumulate over time.
Water deposits sediment through a process called sedimentation where particles carried by the water settle on the bottom of a water body. This can happen when the velocity of the water decreases, allowing the particles to drop out of suspension. Over time, sediment can accumulate and form layers on the bottom.
Wind or water carrying sediment deposits its load in slow moving or standing water. Sediment typically comes from beaches, erosion, and typical weathering.

The triangular-shaped landforms caused by deposited sediment are called deltas. Deltas typically form at the mouth of rivers where the flowing water slows down and deposits sediment, creating a triangular shape as it spreads out into a larger body of water like a lake or ocean.
Alluvial deposits are formed when water transports and deposits sediment, such as sand, silt, and gravel, in low-lying areas like riverbeds, floodplains, and deltas. These deposits accumulate over time as the water flow decreases and the sediment settles.
These are called alluvial fans. They are typically composed of coarse sediment like sand and gravel, which is carried down mountainsides by fast-flowing streams and rivers and then spread out in a fan-like shape as the water loses energy and deposits the sediment.
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.
