Q. Consider the following statements regarding Peneplain:
1. It is formed due to erosion by rivers and rain.
2. When a peneplain is raised, it becomes a Plateau.
Which of the statements above given is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C
Notes:

Peneplain is a region that is almost a plain. It is formed due to erosion by rivers (stream erosion) and rain, that continues until almost all the elevated portions are worn down; the most resistant rocks generally stand above the general level of the land.  

When a peneplain is raised, it becomes a Plateau, which is then dissected by the river as they pass through a fresh cycle from youth to old age.
