What is the role of sheet floods in a desert pediment?
Answer and explanation
Correct answer: They form sheets of shallow flow that erode and deposit across the foot slope
A desert pediment is a gently sloping, rock-cut surface at the foot of a mountain. During intense but short-lived storms, water spreads outward as a thin sheet rather than remaining in one channel. This sheet flow strips and smooths parts of the surface and deposits sediment in lower areas, helping widen and develop the pediment. Hence option A is correct; the other choices describe unrelated coastal, glacial, or karst processes.
