Which of the following depositional landforms is formed by the accumulation of sediment where a fast-flowing stream emerges from a mountain canyon onto a flat plain?
A. Moraine
B. Alluvial fan✓ Correct Answer
C. Oxbow lake
D. Barrier island
💡 Solution & Explanation
An alluvial fan is a depositional landform created when a high-velocity stream emerges from a constricted mountain canyon onto a flat lowland plain, losing velocity and depositing sediment in a fan shape. Landforms like oxbow lakes are formed by meandering river dynamics in mature valleys rather than mountain exits. These geological features are typical characteristics of arid and semi-arid piedmont zones worldwide.
