Peneplains and Pediments
Introduction:
Peneplains and Pediments are important geomorphic features. They have different characteristics and are formed due to different processes. This question aims to test the candidate's knowledge regarding these two features.
Explanation:
- Peneplains are erosional plains: Peneplains are a type of erosion surface that has been worn down almost to the level of the surrounding landscape. They are formed due to prolonged weathering and erosion processes. The term "peneplain" comes from the Greek words "penē" meaning almost, and "plainē" meaning level land. Peneplains are usually found in areas of low relief, such as old mountain ranges, and are characterized by a smooth, rolling landscape with few sharp peaks or valleys.
- Pediments are depositional plains: Pediments are gently sloping, broad aprons of sediment that form at the base of mountains or hills. They are formed due to the deposition of sediments that are eroded from the mountains or hills above. Pediments are usually found in arid or semi-arid regions, where there is little vegetation to hold the soil in place and where erosion rates are high.
Conclusion:
Based on the above explanation, it is clear that statement 1 is correct and statement 2 is incorrect. Therefore, the correct answer is option A, i.e., 1 only.

Consider the following statements:1. Peneplains are erosional plains2...
These plains are carved by the agents of erosion. Rain, rivers, ice and wind help to smooth out the irregularities of the earth's surface, and in terms of millions of years, even high mountains can be reduced to low undulating plains. Such plains of denudation are described as peneplains a word meaning ‘almost plains'. Pediments and pediplains are erosional plains.
