Alluvial Fan

A fan-shaped deposit formed as water flows down a slope
Real World Example
Imagine you're carrying a tray full of marbles and accidentally trip, causing the marbles to scatter across the floor in a fan shape. This scattering is similar to how an alluvial fan forms when water, carrying sediment, flows down a slope and spreads out at the base. Just like the marbles spreading out when the momentum is lost and they encounter the resistance of the floor, the sediments in an alluvial fan are deposited in a fan shape as the water slows down and spreads out on flatter ground.
