What is the fan-shaped depositional feature at the foot of a mountain slope called?
Answer and explanation
Correct answer: Alluvial fan
An alluvial fan forms where a stream leaves a steep mountain valley and reaches flatter ground. The sudden decrease in slope and speed reduces the stream’s carrying capacity, so gravel, sand, and silt spread outward in a fan-shaped deposit. Thus option A is correct. A sea arch is wave-eroded, a glacial valley is ice-eroded, and a stalagmite grows upward from a cave floor.
