Quizplus · Accepted Answer

Cone-shaped deposits of sediment found at the mouth of canyons in arid and semiarid climates are called alluvial fans. These fans form when water carrying sediment flows down a steep slope and spreads out onto a flat area. The sediment is then deposited at the base of the slope, creating a cone-shaped deposit.
