Question

Quizplus · Accepted Answer

Alluvial fans are cone-shaped deposits of sediment that form at the mouths of canyons in arid and semiarid climates. They are created by the deposition of sediment carried by water that flows down the canyon and spreads out onto the lower, flatter land at the base of the canyon. The sediment is usually composed of a mixture of gravel, sand, and silt.
