A fan-shaped pile of sand forms due to the process of sediment deposition, typically influenced by wind or water flow. As the wind or water slows down, it loses the energy needed to carry the sand particles, causing them to settle in a radiating pattern from a central point. This results in a broad, sloping shape, similar to a fan. The angle of repose and the consistency of the sand also play crucial roles in determining the final shape of the pile.
When the students created a small pile of sand at the end of the flow of water, they modeled the formation of a delta. Deltas form where rivers deposit sediment as they slow down upon reaching a larger body of water, creating triangular or fan-shaped landforms. This process illustrates the principles of sediment transport and deposition in a riverine environment.
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.
fan shape
Splay sand refers to sand deposited by wave and tidal action in a beach environment, creating fan-shaped patterns. It is formed through the transport of sand by the water's energy, which causes the sand to spread out in a radiating pattern as the water recedes. Splay sands are typically found in intertidal zones where waves and currents are strong enough to shape and move the sand particles.
Only plants that have been trained by pruning will form a fan shape. Trees such as apples, peaches cherries etc. can be fan trained against a wall to protect from severe weather.

A structure built up by stream deposits at the foot of a mountain is called an alluvial fan. Alluvial fans form when rivers or streams carrying sediment from the mountains suddenly lose velocity and deposit the sediment in a fan-shaped pattern.
Its coral fin not coral fan! Actually, it IS coral fan! Coral Fans, also known as sea fans, are more correctly called Gorgonians. They are colonial soft corals which grow in a "fan" shape and anchor in sand instead of on hard surfaces as hard corals do. Their primary predators are fish such as, but not limited to, angelfish and butterfly fish. They eat plankton which they capture as it drifts past them.

an alluvial fan
A delta forms from the deposition of sand and silt particles carried by a river as it enters a larger body of water, such as an ocean or lake. Deltas typically have a fan-like or triangular shape and provide valuable habitat for various plant and animal species.
