Which of the following describes a pediment in geomorphology?
A. A steep-sided, flat-topped hill formed by differential erosion in arid regions
B. A gently inclined rock-cut bedrock surface found at the foot of retreating mountain slopes in arid or semi-arid regions✓ Correct Answer
C. A depositional landform created by wind-blown silt accumulation in semi-arid plains
D. An alluvial fan formed at the mouth of a canyon during flash floods
💡 Solution & Explanation
A pediment is a gently sloping erosional bedrock surface formed at the base of retreating mountain fronts in arid and semi-arid environments. Mesa landforms define flat-topped hills, whereas loess represents wind-blown silt accumulations. Arid geomorphology terms are common in physical geography evaluations.
