What is a peneplain?

• A. A deep valley formed by glacial activity
• B. A large flat area of land
• C. An elevated area of land
• D. A coastal landform

Answer: (B)

A peneplain is characterized as a large flat area of land that has been shaped by extensive erosional processes over a long period of geological time. It represents a nearly level landscape that has been reduced to a base level due to the wearing down of hills and mountains through weathering and erosion. Peneplains often develop as a result of the continuous erosion and are typically found in regions that have experienced significant geological stability after undergoing various geological processes. In contrast, the deep valleys that may be formed by glacial activity are indicative of other landforms rather than the flat surfaces associated with a peneplain. Elevated areas of land and coastal landforms are also distinct landscapes that do not share the characteristics associated with peneplains. Understanding these distinct features helps clarify the concept of a peneplain within the broader study of geomorphology and landscape formation.
