Which outcome occurs when an arid mountain range sheds sediment onto a flat plain?

💡 Explanation

An alluvial fan builds when sediment is deposited onto a plain. The depositional process occurs because a decrease in stream gradient reduces transport competence; therefore, an alluvial fan, rather than increased erosion, becomes typical of this scenario.
