Which of the following statements about desert erosional landforms is/are correct?
1. Mushroom rocks are formed by water erosion and are typically found in glacial valleys.
2. Table rocks have a broad, flat top supported by a narrow base, resembling a plateau.
3. Pedestal rocks are remnants of resistant rocks shaped by wind deflation and abrasion.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Only 3.
Statement 1 is incorrect as Mushroom rocks are products of wind erosion, not water or glaciers. Statement 2 is technically flawed because "Table rocks" (often confused with Zeugen or Mesas) are defined by horizontal strata where the caprock is wider than the base; however, the term "Table rock" is more a descriptive plateau-like feature rather than a specific wind-eroded narrow-based landform. Statement 3 accurately describes Pedestal rocks as remnants shaped by wind abrasion (sandblasting) and deflation.
