Question

Quizplus · Accepted Answer

An alluvial fan is a depositional feature that forms at the base of a steep slope or mountain, where a canyon or gully opens out onto a flatter plain. As runoff and sediment flow down from the canyon, the water slows down and spreads out, losing energy and depositing sediment in a fan-shaped pattern. Alluvial fans are common in dry areas like deserts, and can be seen at the mouths of many desert canyons. Choices A, B, C, and E are not correct because they do not refer specifically to the depositional feature that accumulates at the mouths of desert canyons.
