1.	Pediment is formed1. at the mouth of river2. in the middle course of river3. at the mountain valley4. None of the above
Answer» Correct Answer - Option 4 : None of the above Pediment: Pediments are erosional surfaces. A pediment develops when sheets of running water (sheet floods) wash over it in intense rainfall events. It may be thinly covered with fluvial gravel that has washed over it from the foot of mountains produced by cliff retreat erosion. Formation of pediments: With the granitic bedrock weathering and stream transport of sediments, pediments emerge spontaneously. Pediment formation is promoted by arid conditions that hinder vegetation, reduce soil cohesion, and contribute to channel bank instability. Localized flooding on terrain with high infiltration rates also promotes pedimentation. These conditions all reduce incision rates. Pediments are more common in hydrologically open basins than in hydrologically closed basins. Hence, the correct answer is None of the above.

Pediment: Pediments are erosional surfaces.

A pediment develops when sheets of running water (sheet floods) wash over it in intense rainfall events.
It may be thinly covered with fluvial gravel that has washed over it from the foot of mountains produced by cliff retreat erosion.

Formation of pediments:

With the granitic bedrock weathering and stream transport of sediments, pediments emerge spontaneously.
Pediment formation is promoted by arid conditions that hinder vegetation, reduce soil cohesion, and contribute to channel bank instability.
Localized flooding on terrain with high infiltration rates also promotes pedimentation. These conditions all reduce incision rates.
Pediments are more common in hydrologically open basins than in hydrologically closed basins.

Hence, the correct answer is None of the above.
