Q. Which of the following statements regarding Pediplain are correct?

1. It is an extensive plain formed by the coalescence of pediments.
2. Cryoplanation is a variant of pediplanation that is restricted to deserts.
3. Pediplains are normally formed in areas of arid and semi-arid climate.

Select the correct option from the codes given below:
Answer: Only 1 & 3
Notes: Pediplain is a landform formed by the coalescence of pediments, typically in arid and semi-arid regions. The process of formation is called pediplanation. Lester Charles King, in 1942, introduced these concepts. Cryoplanation is a variant of pediplanation occurring in cold regions, not deserts. Thus, only statements 1 and 3 are correct.
